Sorry for the off-topic and a mistake about letter Щ in Serbian:

I have to make correction! Щ doesn't exist in Serbian, so there's no equivalent in Croatian (using Latin alphabet), only in Bulgarian and is pronounced SHT, like mentioned before.

See Serbian alphabet:

Here you can find mapping between Cyrillics and Latin used in Serbian, Croatian and Bosnian

Cyrillics is used in Serbia, Montenegro, Serbian part of Bosnia-Herzegovina and Macedonia (they use their own Macedonian language)
