U+302A "〪" Ideographic Level Tone Mark Unicode Character

Unicode Version 17.0

U+302A "〪" Ideographic Level Tone Mark is a diacritical mark used primarily in the context of East Asian scripts, specifically within the CJK (Chinese, Japanese, and Korean) block, to indicate a level tone in phonetic notation of Chinese characters. It is part of a set of tone marks that were historically employed in certain dictionaries and linguistic texts to represent the four classical tones of Middle Chinese, with this particular mark denoting the first or level tone. The character appears as a small, horizontal stroke placed above or to the side of a character, and it is encoded for compatibility and use in specialized textual applications rather than in everyday writing.
