In Windows, whenever I am facing an incorrect display of non-unicode characters (for me usually Russian (Cyrillic) characters may get displayed as ancient runes =), I go to regional settings, set Russian as a System Locale for Non-Unicode applications and the problem is solved after restart.
In OS X, in iTunes, I have added a music album by Russian band, and all the text string (sone names) are displayed incorrectly. Overall all other russian albums in iTunes are getting displayed correctly.
Where can I tune up my OS X to diaplay Russian all the way?
