This is probably a Mac OS X rather than a Jaikoz issue but I am sure someone can help since I cannot be the first of your users encountering it.
After updating my Mac Mini earlier this year Jaikoz will not read folders with foreign language characters so tracks with French, German or Spanish accents are now ignored.
This is obviously problematic. As far as I can see the character-set on my Mac Terminal setting is correct. What am I missing?
