U+302D "〭" Ideographic Entering Tone Mark Unicode Character

U+302D "〭" Ideographic Entering Tone Mark is a small, dot like diacritic used in Chinese character notation to indicate the entering tone, or rusheng, a syllable that ends in a plosive consonant such as p, t, or k. It is part of the CJK Symbols and Punctuation block and is typically placed to the right of a Chinese character in vertical text or below it in horizontal text, serving as a phonetic guide in historical or scholarly contexts. This mark helps readers identify truncated pronunciations that no longer exist in standard Mandarin but are preserved in some dialects like Cantonese and Hakka.
