Dear Hans (or anyone else), There are some fonts (including Lucida) that don't have all the needed character. A font feature "compose=yes" has been added to MKIV, but that one doesn't work for Lucida or any other Type1 font. My current fallback is to use: % this doesn't help % \definefontfeature % [compose] % [liga=yes,kern=yes,tlig=yes,compose=yes] \beginNEWTEX \catcode`č=\active \catcode`Č=\active \defč{\buildtextaccent\textcaron c} \defČ{\buildtextaccent\textcaron C} \endNEWTEX But nevertheless a few questions: - Is there some "accessible" method to compose a few characters in the font (not too low-level) as opposed to using active characters? The code must be there already since this is supposed to work for OpenType fonts. - Is there any way to fix horizontal and vertical position of accents (on glyph-per-glyph basis; that one probably needs to be slightly more low-level; maybe using lfg files)? - Do lfg files work for non-opentype (Type1) fonts? Thanks a lot, Mojca
