ID Continue - Yes
Yes is the designation for characters that are permitted to continue an identifier in programming languages and text processing, meaning they can appear after the first character of a name. This includes letters, digits, combining marks, connector punctuation like underscores, and certain other symbols, but it excludes characters that only start identifiers, such as those used for initial letters in some scripts. The condition ensures that identifiers can be extended with numeric or diacritic elements without breaking syntactic rules. For example, Latin letters, Arabic numerals, and the underscore all qualify, while spaces, hyphens, or punctuation like periods do not. This value is determined by a systematic set of rules based on character types and specific exceptions, making it essential for lexers and parsers to correctly recognize valid variable names, function names, and other user-defined tokens across diverse writing systems.
