- Bugs in EP. Oct. 30, 1984 -- Greg Lee
-
-
- A "node" specified in the very first output line, or before that line,
- is misplaced (it's put on the preceding page).
-
- Multiple conditional hyphens in a single word cause confusion when EP
- attempts a line break at any hyphen after the first. Sometimes no
- hyphen is printed, and if it is, it may stick out past the right margin.
-
- A soft hyphen in a $kern string should be ignored, but it isn't. Of course
- one wouldn't type one in, since it wouldn't make sense, but one could be
- inserted if you're using a program to insert soft hyphens.
-
- The presence of a $heading, maybe combined with the beginning-page
- command, and the presence of a duplex font may cause weird scrambling of
- lines at the top of a page. I don't understand this.
-
- Text files are always treated as though they ended with a CR-LF, whether or
- not they actually do. This is not a bug, but you might need to know about
- it when using embedded files.
-
- The top parts of aligned small characters that are italicized or
- bent are not printed properly.
-
- Regular eight point characters on the same line as tall characters
- are not printed properly when the character-height has been set to
- 24 points or more (for duplex characters, the figure is 48 points or more).
- I am not going to be able to fix this.
-
- Duplex characters are affected by the setting of character-height.
- For character-heights of:
- 8 points or less - they are printed at 16 points (just as
- for a setting of 16 points)
- more than 8, less than 16 points
- - less space is left between lines, but
- the characters are not reduced in size
- 16 points - normal
- 17 to 32 points - they are vertically stretched up to the
- appropriate size
- 48 to 96 points - they are vertically stretched up to the
- appropriate size
- The above is a statement of a program extension -- not a bug. Now here
- are the bugs:
-
- Raised duplex characters are not correctly italicized or bent.
-
- Tall characters on the same output line as duplex characters,
- for character-heights greater than 16 points, are stretched up to
- only half the character-height specified.
