What is the status of UTF-8 support?

About a year ago, I used some paches from the following link
to use UTF-8, for namely smbfs.

Does anyone know the current status of unicode/utf-8 handling
in the filesystems in the CURRENT?

Are these patches applied?

Did anyone do anything else on multi-byte related issues?

Thanks,
Hiro
