Uppercase ssharp with XeTeX and LuaTeX

Uppercase ssharp with XeTeX and LuaTeX

[Wolfgang Schuster]

Hi,

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.

This was no problem in the past with pdfTeX because it contained a SS character
for this problem and the output is what I want but I have no solution
for the other
two engines.

\starttext
\WORD{Grußwort}
\stoptext

Greetings
Wolfgang

  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.

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

Best wishes,
Taco

there is one in teh unicode libs, isn't it?

anyhow, when uppercasing, i also check if the font has the characters
