Terminal Punctuation - Yes

Yes is a binary flag indicating that a character functions as terminal punctuation, meaning it typically marks the end of a sentence or clause in written text. This includes characters like periods, question marks, exclamation points, and certain full stops from various scripts, such as the Arabic full stop or the Devanagari danda. The value applies to punctuation that is conventionally used to conclude a declarative, interrogative, or exclamatory statement, and it helps software determine where a sentence boundary occurs for tasks like text segmentation, line breaking, or speech synthesis. Characters with this value are distinct from those that merely separate words or phrases, as they specifically signal a strong final pause or a closing intonation in typography.
