When using input like the following with xetex then harfbuzz kicks in and one would always get the good looking precomposed U+1EA0 for the A and the decomposed B+U+0323 for the B.
With context (and lualatex) one get a rather bad looking -- as the dot is misplaced -- output for the A^^^^0323 input and no output at all for ^^^^1e04. As the coverage for precomposed glyphs varies a lot across fonts this is rather a nuisance. Is there a way to get the fontloader (also the one used by luaotfload) to do a similar substituation as done by harfbuzz? \starttext \catcode`\^= 7 Ạ A^^^^0323 %decomposed input -> U+1EA0 with xetex Ạ ^^^^1ea0 %precomposed input Ḅ B^^^^0323 %decomposed input ^^^^1e04 %precomposed input -> B+U+0323 with xetex \stoptext (I added the ^^-notation to avoid problems with copy&paste) -- Ulrike Fischer http://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
