is there a solution for ssharp with XeTeX and LuaTeX, I have a word with a ß in it which I convert into uppercase letters and the ß remains a lowercase characters.

The problem is that there is no uccode for ß (U+00DF) in char-def.lua and that Mark IV has no way of taking care of this for the moment. But there should be, of course.

I was indeed hoping for a little bit Lua magic to have a working solution but in this case I prefer something that could be used as argument for the style key in \doattributes. \unprotect \definesystemvariable{xx} \def\setupcommand {\dodoubleargument\getparameters[\??xx]} \def\startcommand{\dostartattributes\??xx\c!style\c!color\empty} \def\stopcommand{\dostopattributes} \setupcommand[style=\it] \protect \starttext \input knuth \startcommand \input knuth\par \stopcommand \input knuth \stoptext It should be possible to say "style=WORD" to get the second text completely uppercase even if the text is taken from a buffer or a macro.

that would become rather messy

you can define a style yourself and hook in the attribute

or do something

\setupcommand[style={\setcharactercasing[1]\it}]

I will try this but don't care too much about this, the style option is only for the americans to have the subject for a letter in capitals. Wolfgang

Actually, a (lua) version of \uppercase that takes Unicode properties into account (instead of just \uccode values) would be very useful ;-)

there is one in teh unicode libs, isn't it? anyhow, when uppercasing, i also check if the font has the characters Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
