function that purges 8 bit text?

function that purges 8 bit text?

[Henning Hraban Ramm]

Hi there!

I try to typeset a roleplaying character sheet as PDF form;
it contains a table of skills, each line is a \SkillField after this 
def:

\def\SkillField#1#2{\bTR\bTD #1\hfill (#2) \eTD \bTD 
\definefield[#1][line][SkillSetup][#2]\field[#3]\eTD\eTR}
e.g.
\SkillField{Climbing}{+8}

becomes a table line like:

Climbing   (+8)  [+8]

Now there are a lot of skills that contain e.g. umlauts, so that 
\definefield[#1] fails.
I don't like to introduce a third parameter.

Is there a possibility to strip all invalid chars from a string, so that
\SkillField{Erzählen}{0} can define a field named "Erzaehlen" or 
"Erzhlen" or "Erzahlen"?
(Sorry, I can't program in TeX.)

If this is not possible, I'll try an optional parameter.

just make me s small test file

there is lots of sanitizing code/trickery out there, but need a simple self 
contained example

Hm, it doesn't really have anything to do with my application (defining 
widget fields), so...

\starttext

\def\MyIndex#1{\index[\CLEAN{#1}]{#1}}

\MyIndex{Ätsch} % should expand to \index[Atsch]{Ätsch} or 
\index[Aetsch]{Ätsch}

\stoptext

it's a three line macro to do this kind of things; however, i decided to install 
yet another expansion handler,

\enableregime[windows] \setupregister[index][keyexpansion=strict]

\starttext
   \index[Ätsch]{Ätsch} test \index{QÄtsch} test \index[ratsch]{RÄtsch} test 
\placeindex
\stoptext

those who really want to know the details can look into the source and grep for 
strict in core-sys.tex

think of something: \reduceargument an accented mess\to \ascii

I will upload a new alpha version in a few hours

Thank you!
Will this also work with field names ( \definefield[Übelkübel]... )?

no, what happens when you do that?

(i can of course add such code in more places)
