Some filenames are not hashable

Upon attempting to hash some music, I've found that some filename characters cause it to fail:-

I'm running on Ubuntu 11.04 , Java 6 OpenJDK

Yeah. This has been around forever that some files show up in listings but then appear to be unavailable to open due to weird chars in the filenames.

I think it's probably a manifestation of this "not a bug" JVM feature:

The long and the short of it is these filenames contain unicode characters that don't exist in the locale that you ran Java in.

Try:
LC_ALL=en_US java -jar fs2client-X.X.X.jar

I'll investigate if I can set the system locale at runtime or in the jar manifest but the claim is that using the system local for directory path strings is baked deep into Java and nobody considers it a bug.

[conicalflask]

Seems like I might be able to do: Locale.setDefault(newLocale);

If you report success with LC_ALL I'll have a play around with the code to set the default locale to en_US or en_UK. The C locale is a bit future resistant it seems.

Well, it is the "C" locale... FWIW, fsfuse checks the locale (though the posix nl_langinfo(CODESET) call) and refuses to start if it's not unicode. Better than loads of random bugs in shift-jis, I decided.

[conicalflask]

Assigned bigman while we wait for feedback about locales.

Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

[conicalflask]

Which locale? en_US is the one to try. I think I was wrong earlier and en_UK doesn't even exist. (it's en_GB)

That was the en_US locale.
