What is "IE"?
This : Й й ?

To my understanding Bulgarian has fewer letters than Russian../.
Check the wikipedia reference I gave above, which says they're used in Bulgarian alphabet (how commonly I would not know). I assume 'IE' and 'I' are phonetic transliterations (unicode descriptions like these are always given in English)
