Linus,

I think that there are only some relatively minor problems with using native names instead of English names. The problems have to do with what happens to web browsers if you go outside the standard English 26 character alphabet.

Fancy characters are simply not legal in URLs. This means that we can't have page names in fancy characters. This isn't a wikipedia thing, it is just the way the Internet works.

If people use local letters, it becomes difficult to do searches. This could be overcome by squashing fancy letters down to latin in the search engine.

Actually, the software could automatically squish fancy letters into Latin automatically for the generation of URLs, for searching, etc. This would be a good solution. However... I am not sure how hard it will be.
