U+201B "‛" Single High-Reversed-9 Quotation Mark Unicode Character

U+201B "‛" Single High-Reversed-9 Quotation Mark is a typographic symbol that resembles an apostrophe or single quotation mark flipped upside down, often used as a closing single quotation mark in certain European languages or as an opening mark in others, depending on context and style. It belongs to the General Punctuation block and is distinct from the more common U+2018 left single quotation mark, as its design is based on a reversed or inverted version of the standard high comma shape, sometimes appearing in linguistic notation or specialized typesetting where directional quotation marks are required. Its primary function is to indicate a quotation within a quotation, following a set of predefined rules in Unicode for paired punctuation, though it is less frequently used in modern digital text compared to the straight apostrophe or standard curly quotes.
