I looked at the code and it actually uses an idea that I had already tried. The problem I couldn't solve was do decompose a glyph. Looking at an context example it seems that context can do it. The B with dot below (U+1E04) ends as BU+0323 in the pdf. But how does context does it?
It uses the Unicode composition information (part of UnicodeData.txt), they’re made into a Lua table in ConTeXt (named char-def.lua, if it hasn’t changed).
I know of char-def.lua but the question was more *how* the information is used and *when*. In an input call back? Through a font feature? -- Ulrike Fischer http://www.troubleshooting-tex.de/
