Variation sequences

edit

The Supplemental Mathematical Operators block has eight variation sequences defined for standardized variants.[3][4] They use U+FE00 VARIATION SELECTOR-1 (VS01) to denote variant symbols (depending on the font):

Variation sequences
Base character Base +VS01 Description
U+2A3C INTERIOR PRODUCT ⨼︀ tall variant with narrow foot
U+2A3D RIGHTHAND INTERIOR PRODUCT ⨽︀ tall variant with narrow foot
U+2A9D SIMILAR OR LESS-THAN ⪝︀ with similar following the slant of the upper leg
U+2A9E SIMILAR OR GREATER-THAN ⪞︀ with similar following the slant of the upper leg
U+2AAC SMALLER THAN OR EQUAL TO ⪬︀ with slanted equal
U+2AAD LARGER THAN OR EQUAL TO ⪭︀ with slanted equal
U+2ACB SUBSET OF ABOVE NOT EQUAL TO ⫋︀ with stroke through bottom members
U+2ACC SUPERSET OF ABOVE NOT EQUAL TO ⫌︀ with stroke through bottom members
