  Computer fonts typically default to the Central/Eastern, Russian letterforms, and require the use of OpenType Layout (OTL) features to display the Western, Bulgarian or Southern, Serbian/Macedonian forms. Depending on the choices made by the (computer) font designer, they may either be automatically activated by the local variant locl feature for text tagged with an appropriate language code, or the author needs to opt-in by activating a stylistic set ss## or character variant cv## feature. These solutions only enjoy partial support and may render with default glyphs in certain software configurations, and the reader may not see the same result as the author intended.
