Re: mapping of XML names into programming language

Hello Paul,

This is a personal answer. This problem was looked at in the
context of XML Schema and XQuery. I remember a solution where
(speaking generally) non-ASCII characters were transformed
to a sequence of characters that included some underscores
and/or dollar marks and the Unicode character number in hex.

I'm not totally sure whether this solution is currently in
a spec or not, the best person to ask is Michael Rys.

Conversions such as the one you mention from Kanji to Romaji
have the advantage that the result is still fairly legible,
but there are various disadvantages:
- large dictionary needed
- not deterministic (there is often more than one way to
   pronounce a Kanji or Kanji combination)
- not reversible (there are many Kanji or Kanji combinations
   that lead to the same Romaji)
- language-specific, which means a different solution for
   each language is needed

I hope this input can lead to a discussion where we understand
your needs better.

Regards,    Martin.
