Reading other alphabets
Greek and Cyrillic look strange at first, but many letters line up with English sounds. Puzzle caches sometimes write English words in these alphabets, or give Greek letter names like gamma and omega that stand for letters.
CacheCrack converts Greek and Russian letters into their usual English spellings, and can go the other way. Some letters become two, like θ to th and ж to zh.
Example
Москва becomes Moskva.
