Are there any more contemporary solutions to this
issue? Ideally I'd
like to have a separate field for URL when creating/editing a page -
is it possible to create a plugin that would allow this? Another
solution would be having this field noneditable and automatically
filled with transliterated name of the page..
We're not likely to ever support something like that.
Remember we're in this for the long haul; browser support for IRIs will continue
to improve. (If you don't like your current browser, try Safari -- it handles
these just fine.)
