isn't that what \enableregime[ec] does?
No, it doesn't (and it would be a magic if it would), but what exactly is its purpose anyway? \ccaron works perfect, but writing č (ccaron) literally doesn't. XeTeX doesn't know what to do with character "010C" (ccaron) since the font only contains glyphs from 0 to 255. But well, the pound sign (£ or ^^a3) will become ccaron eventually since A3 (Unicode slot for a pound) is ccaron in EC fonts. What would be needed is a list of (something less than) 256 mappings from Unicode to named glyphs (or perhaps the whole latin repertoair).

I can prepare extensive tests, but the attached file (csz.tex) should be enough for basic testing. No other font definitions are needed since EC is the default font anyway, but you can try with \font\A='Arial' \A or something similar. Recipe nr. 1 ---------- In \enableregime: if XeTeX is used, do \XeTeXinputencoding "bytes" before reading the regime file. Pros: * exactly the same behaviour as in pdfTeX * accented characters will work OK with EC font * both regimes and ec fonts will become obsolete one day: this approach works OK for both of those 'to-become-obsolete' stuff Cons: * \font\A='some unicode font' \A might not work out-of-the-box (uc encoding has to be specified for the font): not so convenient, but high-level macros can be used * no support for some exotic regimes yet (Hewbrew, Arabic, ...): not so serious since they probably use Unicode anyway and they can be added if needed Recipe nr. 2 ---------- In \enableregime: if XeTeX is used, do \XeTeXinputencoding "argument of enableregime" and don't read regime file. Pros: * support for exotic regimes out-of-the-box (those regimes most probably need OpenType fonts anyway) * works perfect with unicode fonts Cons: * most probably doesn't work with EC fonts without additional tweaking
here i get the right characters when i say:
I don't have XeTeX on this computer, but ...
\starttext
\XeTeXinputencoding "utf8"
I never tried it, but isn't this the default one?
It works! [\eacute][\rawcharacter{233}][Ã(c)]
\yen
\yen is OK. It's literal ¥ (or ^^a5) the one that results in "random glyph" (ie. the one that is located under a5 in the current font encoding). I don't know what happens with the last one, but from the experience I would guess that it would be left blank.
\XeTeXinputencoding "bytes" % \enableregime[ec]
It works! [\eacute][\rawcharacter{233}][é]
This works under assumption that one is using EC input encoding (which is never the case). But yes, \XeTeXinputencoding "bytes" \enableregime[cp1250] would be almost OK. Mojca
