I'm trying (once again) to find out if learning something about XeTeX is worth the trouble. So far, I haven't seen any compelling reason, but I'd like to experiment a bit more. Here are two questions I have run into: 1. in the wiki pages "Talk:XeTeX," there's this anonymous piece of wisdom: Referencing fonts by filenames (just a note from the XeTeX mailing list as a reminder for later) in texmf.cnf: OPENTYPEFONTS = .;$TEXMF/fonts/opentype//;c:/Resources/Fonts// Then \setromanfont{[KalligraphiaLTStd.otf]} Is this possible or usable in ConTeXt? I have lots of OpenType fonts in ~/texmf/fonts/opentype, but not installed as system fonts, and would like to see whether they can just be used with XeTeX as with vanilla pdftex. texmf.cnf is set up accordingly, but so far, I haven't had any success. 2. When generating the formats, texexec complained about "unknow control sequence" because of lines 25 and 26 in syst-xtx.tex \setcclcuc 201C 201C 201C \setcclcuc 201D 201D 201D I had to comment out these lines to generate the formats (this is with a texlive2007 snapshot of last week and the latest ConTeXt). Is this a known bug? All best Thomas
