Comment 10 for bug 368626

I'd rather have my filenames left as is.
I believe some script built to perform the "migration" from old encoding to new utf-8 might be a better alternative.
I have some filenames living here from koi8-r era of my linux installation and doing iconv-things is not user-friendly.
Maybe a cmdline app and GUI for it for those that have no idea why some files they have are invalid.

But the first thing to do in this case is to notify the user that not all of his files can be synced. Skipping that silently/writing a warning to log only will cause more bug reports about incomplete syncing.
