Variation sequences
The Supplemental Mathematical Operators block has eight variation sequences defined for standardized variants.{{Cite web|url=https://www.unicode.org/Public/UNIDATA/StandardizedVariants.txt|title=Unicode Character Database: Standardized Variation Sequences | publisher=The Unicode Consortium}}{{citation|url=https://www.unicode.org/L2/L2000/00119-math.pdf|title=L2/00-119: Encoding Additional Mathematical Symbols in Unicode|section=Symbol variants defined using a Variation Selector|date=2000-04-19|first1=Ken|last1=Whistler|first2=Asmus|last2=Freytag}} They use {{sc2|U+FE00 VARIATION SELECTOR-1}} (VS01) to denote variant symbols (depending on the font):
