Needs language-specific mode.
Turkish has special rules on capitalization for the letter I/i.
Unlike most languages, where I <-> i, Turkish has separate dotted and dotless versions of the letter I, and the capitalization mapping is I <-> ı and İ <-> i.
If an album language is marked as Turkish, Guess Case should use this alternate mapping.
Regardless of the album language, Guess Case currently performs the mappings ı -> I and İ -> i; this is correct, and should not change.
Note: this should be applied to Azerbaijani, Crimean Tatar, Kazakh and Tatar too, although their use in MB is probably much lower.
