Unicode variation selector (tsz. Unicode variation selectors)

  1. (informatika) Variation selectors are encoded in three Unicode ranges scattered across the planes. Their purpose is to mark variations of a character in certain cases where it may be appropriate to specify one form of a character. The variations are not arbitrary, but specifically listed in the Unicode standard. There are currently three main uses of variation selectors:

Variation selectors 1-16 are encoded in the U+FE00-U+FE0F block. Only the first three and the last two are ever actually used in Unicode. The first (VARIATION SELECTOR-1, U+FE00) is used for many different characters from several scripts, while the second (VARIATION SELECTOR-2, U+FE01) and third (VARIATION SELECTOR-3, U+FE02) are used only for variant forms of Han ideographs. The last two are used to specify text (monochrome) or emoji forms of characters; VARIATION SELECTOR-15 (U+FE0E) selects the text form, while VARIATION SELECTOR-16 (U+FE0F) selects the emoji form. Variation selectors 17-256 are encoded in the U+E0100-U+E01EF block. This set is intended to define special variants of Han ideographs. The Mongolian block has its own set of variation selectors which is used orthographically in this script.
