ID Start - Yes

Unicode Version 18.0

Yes is the designation for characters that can begin an identifier in programming languages and text processing systems, meaning they are valid starting points for variable names, function names, or other syntactic tokens. This includes letters from all scripts (like Latin, Greek, Cyrillic, Arabic, and Han), as well as certain other characters such as the underscore, and some symbols defined as acceptable by Unicode’s rules. Characters marked “Yes” are typically those with general categories like uppercase, lowercase, or titlecase letters, along with modifier letters and letter numbers, but they exclude digits, punctuation, and most symbols. The value ensures that identifiers are unambiguous and consistent across different languages and platforms, allowing for internationalized code while preventing confusion with numeric or operator characters.
