MACINTOSH KERMIT FONTS: PROPOSED DESIGN
Frank da Cruz, Columbia University
Last update: Wed Jun 3 11:38:28 1992
The present Mac Kermit font (Mac Kermit version 0.99(94) and earlier) has
numerous problems: it's ugly; it doesn't scale well (or at all) to sizes other
than 9 or 18 points; its code points for accented letters and other special
characters don't agree with standard (or more precisely, Quickdraw) encoding;
and it is internal to Mac Kermit only, so (a) can't be seen from keycaps, and
(b) can't be used by other applications.
The goal is to replace Mac Kermit's built-in font with a new one that can
be used for true international-version VT320 emulation:
1. Built into Mac Kermit, but also available as an external font for use
with other applications, by Keycaps, etc.
2. Available in a variety of sizes (such as 7, 9, 10, 12, 14, and 18).
3. Contains all the characters of ASCII, ISO 8859-1 Latin Alphabet 1, and the
DEC Multinational Character Set, as well as the characters of all the
7-bit National Replacement Character sets (NRCs) supported by the VT320:
British, Canadian French, Dutch, Norwegian, German, Finnish, etc etc,
most of which are also in Latin-1.
4. The code points of the characters in (3) correspond to the code points
for the same characters in the Apple Quickdraw character set, so (for
example) Kermit-font international text, when converted to (say) Courier,
will still read correctly (a-grave will still be a-grave), at least for
all the characters that the two sets have in common.
5. The invertible mapping between Latin-1 and the text portion of the Mac
Kermit character set will be used for both terminal emulation and file
transfer. The full translation must be invertible over all 256 bytes.
6. DEC Special Graphics, DEC Technical Set, and "display controls" characters
must be available, and mixable on the same screen with text font.
7. Screen fonts should be ordinary bitmap fonts for compatibility with old
System versions, etc. Printer fonts are Type-1 PostScript fonts. There
should be no dependence on System 7, Suitcase, TrueType, etc etc.
8. Regular and bold versions are needed. (Note: Mac Kermit's present
VT100 font also has an Italic style, which is used in lieu of the VT100
"blinking" character attribute -- I don't know why.)
This document proposes such a character set and font. It is hoped that Apple
will recognize this (perhaps in amended form after discussion and further
work) as the official representation for Latin-1 on the Mac, to promote
interoperability with other Mac applications that need a Latin-1 character
set. Or else Apple should publish its own official Latin-1/Mac mapping.
THE MACINTOSH KERMIT VT TERMINAL EMULATION FONT
On the Mac, a font is a particular character set (Standard, Quickdraw, Symbol,
or other) rendered in a particular style, with variants for italic, bold,
underlined, shadow, etc. A font may have at most 256 elements.
A major problem we face right now is that Mac Kermit's "VT100" font is not
encoded like other Mac fonts. So even if you manage to get a correct-looking
display of your Swedish or French text on the screen, if you change the font
from VT100 to (say) Courier, all the accented characters become garbage. We
have to recode Mac Kermit's fonts to remove this problem.
We can't just substitute, say, Courier for Mac Kermit's VT100 fonts because
Courier lacks certain characters from Latin-1. And we also have to support VT
terminal characters that aren't available in any Mac fonts.
For the current level of terminal emulation, we need to support ASCII (95
graphic characters, including space) plus Latin-1 (96), plus DEC Special
Graphics (33) plus DEC Technical (94), plus Display Controls (64) = 382
characters. In addition, we might also wish to support DEC MCS, which is
identical to Latin-1, except it includes OE/oe ligatures instead of multiply
and divide signs, and lacks the Icelandic characters and several others. This
would raise the total number of characters needed by Mac Kermit to about 384.
We also want a complete set of "display controls". These are graphic
representations for each control character that fit in a single character
cell, for example a small "CR" to represent Carriage Return, a small "LF"
to represent Linefeed. A Display Control character is made of two small
characters representing an abbreviation of the control character mnemonic,
arranged like this within the character cell:
+--+
|L |
| F|
+--+
ISO Standard 6429 names and describes the 8-bit control characters used by the
VT200-300 series of terminals. These are also listed in the VT200-300 series
manuals. The complete list of display controls is found in these manuals.
For the C1 display controls, DEC simply uses the hex value 80, 80, ... 9F, for
example:
+--+
|9 |
| F|
+--+
Thus there are 65 display control characters: 0-31, 127-159.
All the required characters can be represented using only two encodings/fonts.
Here is a possible design.
Font "A" (Let's call it Macintosh Extended Latin). This is the "text font".
. Characters 0 through 31 and 127 are display controls.
. Characters 32 through 126 are ASCII.
. Characters 128 through 255 are as follows:
Characters from Latin-1 and DEC-MCS that also exist in QuickDraw encoding
use the QuickDraw encodings. Merge SPACE and NO-BREAK SPACE for the
purposes of display -- they look the same. Define all remaining Quickdraw
positions as "unused". There are 47 of these.
Characters from Latin-1 and DEC-MCS that do NOT exist in QuickDraw are
created and inserted in unused positions, rendered in the same style.
These are:
ISO Name PostScript name
broken vertical bar /brokenbar
superscript 1 /onesuperior
superscript 2 /twosuperior
superscript 3 /threesuperior
fraction 1/4 /onequarter
fraction 1/2 /onehalf
fraction 3/4 /threequarters
Icelandic thorn /Thorn, /thorn
Icelandic eth /Eth, /eth
Y-acute /Yacute, /yacute
Multiply /multiply
This makes a total of 14 characters. 47-14 = 33, enough for
The C1 controls, which should be left undefined.
Font "X" ("VT Special?"): VT special graphic characters, display controls, etc:
The DEC Special Graphics set is a 7-bit 94-character set identical to ASCII
except in columns 6 and 7, so 32 new characters are needed: box corners,
diamond, plus/minus, less-equal, greater-equal, not-equal, etc, plus character
137 (5/15) is blank instead of underline. It is described in all DEC terminal
manuals, VT100 and later. This set is currently supported by Mac Kermit. The
final character of the designation sequence is "0". Because it is a 94-byte
set, it can be designated to any of G0..G3:
ESC ( 0 designates the DEC Special Graphics set to G0
ESC ) 0 designates the DEC Special Graphics set to G1
ESC * 0 designates the DEC Special Graphics set to G2
ESC + 0 designates the DEC Special Graphics set to G3
The DEC Technical Set, which is also currently supported by Mac Kermit, is
described in the DEC VT320 and 340 Programmer Reference Manual, Volume 1,
page 27, Figure 2-8. It is a 94-byte set that can be designated to any of
G0..G3. The final character of the designation sequence is ">":
ESC ( > designates the DEC Technical set to G0
ESC ) > designates the DEC Technical set to G1
ESC * > designates the DEC Technical set to G2
ESC + > designates the DEC Technical set to G3
NOTE: the DEC Special Graphics and Technical character sets and final
character of their designation sequences are NOT registered with the ISO, and
therefore the final characters "0" or ">" might conflict with those of a
registered set.
So "Font X" can have the following very natural layout:
0-31: C0 Display Controls (NU, SH, SX, ... US)
32-126: DEC Special Graphics (32-94 are the same as ASCII)
127: Display control for Delete
128-159: C1 Display Controls (hex)
160: UNDEFINED
161-254: DEC Technical Set
255: Display control for 127 (DT).
This design means that Kermit's internal terminal character set translations
will also have to change. Kermit will now have to translate characters during
the terminal i/o process (port to screen, keyboard to port). It will NOT have
to translate during print-screen or cut-and-paste operations.
The display-control graphics are used only when the user has checked the
"Symbolic Control Characters" box in Mac Kermit's Terminal Settings dialog.
When the user selects a different font from the font menu, that font replaces
only Font A -- Font X is always loaded internally, and selectable by menu
assignment or host escape sequence (e.g. ESC ( 0 for DEC Special Graphics).
Kermit's normal mappings and translations continue to apply to Font A
characters, so it's up to the user to pick a font that makes sense, or check
"terminal character-set transparent". This is a nice feature because it
allows users to extend Kermit to support additional character sets just by
selecting new fonts (as Font A) in Kermit's Font menu, and still maintain VT
terminal compatibility, display controls, etc.
Using this design, it should be easy to add support for other 8-bit sets: for
example, Font B might be based on ISO 8859-2: "simply" copy Font A and replace
characters 160-255 with those from Latin-2, retaining the greatest possible
encoding correspondence with whatever Macintosh encoding is used in Eastern
Europe (if any).

To allow both Latin-1 and DEC MCS terminal character sets, we should also
include the OE/oe ligature, which occupies the same code points in DEC MCS
as the Latin-1 division and multiplication signs:
DEC-MCS OE digraph (215) 206 206
DEC-MCS oe digraph (247) 207 207
This leaves us with the following empty QuickDraw code points:
1. 160 Dagger
2. 165 Center Dot (fat)
3. 170 TM (not circled)
4. 173 Not equals
5. 176 Infinity
6. 178 <=
7. 179 >=
8. 182 delta
9. 183 Sigma
10. 184 Pi
11. 185 pi
12. 186 Integral

28. 220 Left angle bracket
29. 221 Right angle bracket
30. 222 fi ligature
31. 223 fl ligature
32. 224 Double dagger
33. 226 Baseline singlequote
34. 227 Baseline doublequote
35. 228 Per mil

41. 250 Dot accent
42. 251 Ring above
43. 253 Hungarian umlaut
44. 254 Ogonek
45. 255 Caron
We need to assign code points for the 15 characters from Latin-1 that do not
exist in QuickDraw. 45 free code points are available, leaving 30 free after
we make these assignments.
Here is a possible mapping of the Latin-1 characters that are not part of the
QuickDraw character set. The mappings are chosen so as to replace the most
"useless" QuickDraw characters, reserving others that might be used in some
future terminal or file character set for possible future use, and also to use
the closest available QuickDraw characters in the few cases where it is
desirable to show something reasonable in case the user displays a "Font A"
file in (say) Courier/QuickDraw (such as center dot in place of multiply).
The Icelandic Thorn and Eth characters are placed at the same positions that
Apple uses on its Icelandic-model Macs.

Superscript one 185 176 /onesuperior
One quarter 188 178 /onequarter
One half 189 179 /onehalf
Three quarters 190 186 /threequarters
Icelandic Eth 208 220 /Eth

Icelandic Thorn 222 222 /Thorn
Icelandic eth 240 221 /eth
y acute 253 224 /yacute
Icelandic thorn 254 223 /thorn
This leaves 30 codes still free. Whatever mapping we choose, it should be the
same as the file transfer character-set mapping, so we can cut and paste
terminal screens and transfer files with the same results.
I learned (the hard way, and with help from Bur Davis at Adobe) that when
constructing a Courier-based PostScript Latin-1 font, certain characters that
are not actually used in Latin-1 must still be present in the font, otherwise
many Latin-1 characters themselves cannot be printed on certain kinds of
PostScript printers (see kermit/charsets/textps.c on watsun).
The problem is that in early versions of PostScript (pre-47.0, I think),
Courier was a "stroke font", in which many of the accented characters are
composed from other characters (for example, i-grave = i-dotless + grave).
Thus dotless i and the various accents must be present in the font. So if our
printer font were to be like Courier, we must allocate at least the following
from our 30 free positions. The suggested encodings are QuickDraw encodings
when the character is part of the QuickDraw character set, otherwise they are
chosen arbitrarily (*).
Suggested
Name Encoding PostScript Remarks
------------ -------- ---------- -------
Grave accent 197* /grave Not in QuickDraw
Dotless i 245 /dotlessi
Circumflex 246 /circumflex
Tilde 247 /tilde Not the same as /asciitilde
Ring above 251 /ring
For future expansion into other Roman-based language groups (East European,
etc), we should also include:
Suggested
Name Encoding PostScript Remarks
------------ -------- ---------- -------
Breve 249 /breve
Caron 255 /caron
Ogonek 254 /ogonek
Hungarian Umlaut 253 /hungarumlaut
Dot accent 250 /dotaccent
L with stroke 220* /Lslash Not in QuickDraw
l with stroke 221* /lslash Not in QuickDraw
And for compatibility with the Dutch ISO 646 variant as well as various
proprietary host character sets (like Data General):
Florin sign 196 /florin
For a total of 14 more characters, reducing our free positions from 30 to 16.
The printer version of Font A should be easy to create: it's simply a
PostScript encoding vector -- the characters are already known to PostScript.
The printer version of Font X will have to be printed as a bit map screen font.
COMPLETE LISTING OF MAC KERMIT TEXT FONT ENCODING
When a character does not appear in Quickdraw, the corresponding Quickdraw
character is named in the rightmost column to show the effect of font changes
between Mac Extended Latin and purely Quickdraw-based fonts.
When a character does not appear in Latin-1, it is marked with a "*" in the
Latin column. All such characters are assigned to the C1 area (128-159).
The PostScript character name is given to facilitate construction of a Mac
Extended Latin PostScript font.
The following table produces an invertible translation between Mac Extended
Latin and Latin Alphabet 1. Sixteen character positions remain unused and
undefined, and may be used for future expansion.

FUTURE EXPANSION
Sixteen positions are free.
Latin Alphabet 2 has 34 characters that are not in Mac Extended Latin.
Latin Alphabet 3 has 22 characters that are not in Mac Extended Latin.
Latin Alphabet 4 has 36 characters that are not in Mac Extended Latin.
Latin Alphabet 5 has 5 characters that are not in Mac Extended Latin.
None of these sets of additional characters except Latin-5 will fit. The
five characters from Latin-5 are used for Turkish:
G-breve, g-breve, S-cedilla, s-cedilla, Uppercase I with dot above.
So by adding these five characters we can also fully support Turkish.
