[Plugin: NextGEN Gallery] Convert non-UTF 8 Filenames

Hello 2 all,

I am using nextgen gallery for a Greek Website that i am building based on WordPress.

Here is my problem.
Most of our images have greek names. (like καλημερα σα?!)
and i need to find a way to auto convert those filenames in order to publish them.

I have tried Upload+ that converts non-utf8 filenames and also convert spaces to _. But upload+ doesn’t integrate with NextGen Gallery upload function.

Has anyone find a solution for this kind of problem ?

Thank you in advance for your time!
