I´ve a big problem. I have some running OES (Linux).

After last rug patch three days ago I can´t create
on three oes ncs servers umlauts (externd characters).

For äääüüüü I got ?????.

I checked this oes servers configs with other configs
but I couldn´t find any differnts in configuration.
Same keyboard maps active utf-8 and language settings, etc

This problem occured at all file systems (nss/xfs/ext2
and we can´t see now files and ordners with umlauts
(extend characters). created before this problem
