uppercasing accented characters, mappings and \WORD

uppercasing accented characters, mappings and \WORD

[Mojca Miklavec]

Hello,

If I use the latin2 encoding (il2), \WORD works OK if I simply type 
accented characters. Under UTF-8, uppercasing \zcaron also works OK, but 
fails if I simply type 'ž'. I saw the \definemapping[il2] and I can 
write a mapping for windows-1250 regime as well, but how exactly is this 
done for unicode, where the character codes exceed 255?

Could perhaps alternatively \WORD, \defineactivetoken or any other part 
of code be extended, so that \WORD would be happy with the typed 
accented characters as well? \Zcaron is already defined somewhere to be 
the uppercased \zcaron, so defining the same for every single 
regime/encoding manually seems redundant and error-prone.

Thank you,
	Mojca

(I don't have any editor to support latin2 under windows (except 
Mozilla), even for unicode vim and Windows are fighting against each 
other, so windows-1250 is the only reasonable thing that I can use 
comfortably.)

It fails because \zcaron expands prematurely. Perhaps this is an option:

   \def\definecharacter#1 #2 %
     {\ifundefined{#1}\unexpanded\setvalue{#1}...

instead of

   \def\definecharacter#1 #2 %
     {\ifundefined{#1}\setvalue{#1}...


(not sure if that would break stuff, but it seems sensible to me).

Cheers,
Taco

that will break other stuff (where we want/need expansion)

Thank you, Taco!

I cannot judge about the elegance of the solution as I have never seen
any elegant TeX macro definitions :), but it works (at least on my
examples) which is the most important part. Also the cp1250 regime
(where no mappings were defined) is now happy with it :)

Just for fun, I also tried it on greek (just copy-pasted some letters
from http://www.unics.uni-hannover.de/nhtcapri/multilingual1.html). It
doesn't work there, but I didn't even expect it to work as I should
probably provide the proper fonts and encodings first anyway. I've
seen some strange Greek stuff a while ago, which could have been
definitions of capitals, but as I neither understand Greek nor "TeX",
I can't judge about it.

Is this still relevant? Well, as it was only 11kb, I attached it anyway.

Thank you,

i'll add a sightly shorter variant to the kernel; i'll also fix teh case 
map tables since they have holes and wrong entries (nobody ever checked 
those chars i never use-)
