 That presents an obstacle in Unicode modeling, as the glyphs differ only in italic versions, and historically non-italic letters have been used in the same code positions.Serbian professional typography uses fonts specially crafted for the language to overcome the problem, but texts printed from common computers contain East Slavic rather than Serbian italic glyphs.Cyrillic fonts from Adobe, Microsoft (Windows Vista and later) and a few other font houses include the Serbian variations (both regular and italic).
