The comic books are not registered according to the file name.

It reminds me of this problem.

I don't know yet if I can find a solution as the problem might come from a linux environment issue (file names encoded in a different charset than the one your system uses), but I'll work on it and let you know if I find one.

I'm still investigating this problem. Could you type the command "locale" on your NAS and post the result here ?
You should get something like that (with different values):



Could you also tell me how you start Ubooquity ? Do you do it manually or is it called by one of the Synology startup script (like the ones in rc.d) ?

And perhaps another lead: the Crashplan application (completely unrelated to Ubooquity but running on Java as well) seem to have the same problem. Here is the solution they offer.
If you choose to try it, please let me know if this works or not (I don't have a NAS so I cannot test it myself).

Solution found: see this thread.
