ID Compat Math Start - Yes

Yes is a designation for characters that are considered compatible with mathematical notation at the start of an identifier, meaning they can be used as the opening symbol in a mathematical expression or variable name without breaking syntactic rules. This value flags characters that, while not purely mathematical themselves, are accepted as starting points in contexts where mathematical compatibility is required, such as in programming languages or formal notation systems. It includes symbols that have a visual or semantic resemblance to math operators or letters, allowing them to function as a valid initial token. The designation helps ensure that such characters are recognized for their potential role in mathematical text, even if they originate from other scripts or symbol sets, by confirming their suitability at the beginning of a mathematical identifier. This applies to various Unicode characters that meet the criteria for compatibility in that starting position.
