Notes

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