Minimserver unable to deal with accented characters

[simoncn]

This can be tricky to sort out. The convmv utility can fix this if the encoding is consistent and you know the charset that was used initially to encode the filenames. I don't know what would happen if you use convmv on a file with some accented characters that are valid UTF-8 and other characters that aren't valid.

You could create a new test folder with copies of a few problem files and try using convmv on this test folder to see if it produces valid filenames.
