I only envision the monospace option as affecting the width of TeX's word and sentence spaces - that is, \fontdimen2, 3, 4, and 7. It wouldn't affect other font metrics. Glyphs would still be set in the widths specified by font; and if those widths happened to be proportional, then there wouldn't BE a monospaced grid; "mim" would probably be narrower than "mmm". It's important not to override the widths of glyphs because of the common case I described earlier of a font that is in some meaningful way monospaced, but doesn't have all characters exactly the same width. For instance, fonts designed for CJK typesetting may have all the Latin characters the same width, and all the CJK characters exactly twice that width. These two lines should be the same width, equal to eight typewriter spaces, despite being six glyphs and two spaces on the first line and just four glyphs on the second line: ab cd ef なになに (and they do line up in the terminal window where I'm typing this) Is that monospace? Well, the spaces between words and sentences in Latin script should be treated as they would for a monospace font; if they are, then there will be a grid structure to the page; but the glyphs are not all the same width. If someone wants to force a proportional font to be typeset as monospace with the glyphs on a grid, I think that's beyond the scope of what XeTeX should support. Such users would be better served by editing the font files before giving them to TeX, and in that case they can make their own decisions about how to deal with the "Where is the glyph within the box?" issue when they do the editing. -- Matthew Skala msk...@ansuz.sooke.bc.ca People before principles. http://ansuz.sooke.bc.ca/
