XID Start - Yes

Unicode Version 18.0

Yes is a binary designation indicating that a character can validly begin an identifier in programming languages and related contexts, according to the Unicode standard. Characters with this value include most letters from all scripts, the underscore, and certain other code points like currency symbols or letterlike numbers, but exclude digits, punctuation, and combining marks. This determination relies on stable identifier criteria that avoid confusable or invisible characters, ensuring cross‑language compatibility. When a character holds this value, it means parsers and compilers can safely treat it as the first element of a variable, function, or class name, without risking syntax errors or semantic ambiguity. The value directly supports logical rules for tokenization in software systems, as it filters out inappropriate starting symbols while permitting a broad range of international alphabets and phonetic extensions.
