Yes Value in Quotation Mark Unicode Property

Yes is the designation for characters that are officially recognized as quotation marks within the Unicode standard, meaning they function to enclose direct speech, citations, or quoted text in various writing systems. This includes curly apostrophes, single and double quotation marks, guillemets, corner brackets, and low-9 marks, among others, across languages like English, French, Chinese, and German. These characters are distinct from typographic apostrophes used in contractions or possessives, as the “Yes” value specifically flags marks whose primary purpose is quotation, often paired with an opening or closing counterpart. The classification helps software correctly identify boundaries for quoted content, enabling features like smart quoting, text-to-speech pacing, and syntax highlighting, while also distinguishing them from dashes, primes, or other punctuation that might visually resemble quotes but lack the same semantic role.
