Croatian language
Standard Croatian is the official language of the Republic of Croatia and, along with Standard Bosnian and Standard Serbian, one of three official languages of Bosnia and Herzegovina. It is also official in the regions of Burgenland (Austria), Molise (Italy) and Vojvodina (Serbia). Additionally, it has co-official status alongside Romanian in the communes of Carașova and Lupac, Romania. In these localities, Croats or Krashovani make up the majority of the population, and education, signage and access to public administration and the justice system are provided in Croatian, alongside Romanian.
Serbian Cyrillic alphabet
Cyrillic is in official use in Serbia, Montenegro and Bosnia and Herzegovina. Although the Bosnian language "officially accept[s] both alphabets", the Latin script is almost always used in the Federation of Bosnia and Herzegovina, whereas Cyrillic is in everyday use in Republika Srpska (and is used only by the Serbs in the country). The Serbian language in Croatia is officially recognized as a minority language, however, the use of Cyrillic in bilingual signs has sparked protests and vandalism.
