For example, the following characters all represent math symbols:
“+” (U+002B PLUS SIGN)
“∫” (U+222B INTEGRAL)
“ϰ” (U+03F0 GREEK KAPPA SYMBOL)
The set of characters that have an
is value of
true is not a strict subset of those for which
true. This includes characters used both as letters and commonly in mathematical formulas. For example, “ϰ” (U+03F0 GREEK KAPPA SYMBOL) is considered both a mathematical symbol and a letter.
This property corresponds to the “Math” property in the Unicode Standard.
