Mathematical symbols (e.g., +, −, =, ×, ÷, √, ∊, ≠). Does not include parentheses and brackets, which are in categories Ps and Pe. Also does not include !, *, -, or /, which despite frequent use as mathematical operators, are primarily considered to be "punctuation".
^ 4.04.14.24.34.4"Table 4-9: Construction of Code Point Labels"(PDF). The Unicode Standard. Unicode Consortium. March 2019. A Code Point Label may be used to identify a nameless code point. E.g. <control-hhhh>, <control-0088>. The Name remains blank, which can prevent inadvertently replacing, in documentation, a Control Name with a true Control code. Unicode also uses <not a character> for <noncharacter>.
