- I have tried both methods described here for the benefit of the
- person who wishes to see on his screen the underdotted b and to
- have it printed as such on his document. Neither of them shows me
- an underdotted b on the screen. Yes, I am in NBLingua. True, when
- I use the CTRL-0 solution suggested and on going into expanded
- mode, I see the ULUD command, showing me that something should
- happen when I print (I haven't). In the case of the compose-key
- solution, I see the letter b follow by a left-pointing arrow atop
- a period. A hex dump, reveals that what I see as a two-character
- sequence on screen, is in reality a four-byte sequence consisting
- of the hex values 62 255 1B 44. (Until now, I have seen mention
- here of three- but not four-byte sequences to represent
- characters on screen.) In any case, neither representation is, I
- believe, the solution desired by the inquirer (whose posting I
- must have erased).
-
- I would suggest that the person try to identify a file in his NB4
- directory which bears the suffix .FNT and a date stamp with the
- date at which he last worked on his customized EGA/VGA Font
- Symbol Pool. If he does not remember the date, he can do a dummy
- modification and check for the current date on the saved file.
- With a little luck it might be a free-standing file of 4096
- bytes. If so, that video font file can be edited to include an
- underdotted b. Possibly, however, it will be a modified version
- of the 57344 byte long NB.FNT. But it may be that neither of
- these situations obtains. In that case, we need the help of
- someone who knows what happens when a new font pool is created.
- Does a new EGA/VGA font get assembled from the contents of NB.FNT
- or does the location of each symbol marshalled into the new pool
- get recorded in a file somewhere which serves subsequently to
- assemble the pool when it is called into use? If the latter
- situation occurs, where is the table of symbol locations found in
- NB.FNT for the new pool get recorded?
-
- I have proven to my satisfaction that NB.FNT can be successfully
- patched. I believe that one can design an underdotted EGA/VGA
- letter and splice it into NB.FNT as a replacement for a character
- that you will never use. If the new printer tables use
- substitution tables, I don't see what you could not use that
- approach to instruct the printer to print an underdotted b by
- means of defining the output for the character as
- <<ULUD>>b<<MDNM>>.
