[Typo3-dev] help needed: charset tables (Asian languages)

[Kasper Skårhøj]

TYPO3 only needs simple string functions to support multibyte charsets.
I think the greatest problem is strtoupper and strtolower. All regex
usage is mostly on tokens in text, nothing else.

Then of course supprot for UTF-8 in the database is needed if you want
search results and ordering to work right. And extensions like
indexed_search would need modification as well.

YOu work in CVS looks good! THanks a lot!
