U+FE55 "﹕" Small Colon Unicode Character

U+FE55 "﹕" Small Colon is a punctuation mark found in the Small Form Variants block, designed as a narrower, more compact version of the standard colon (U+003A) for use in East Asian typography and vertical writing contexts. It is intended to blend seamlessly with the line spacing and visual proportions of CJK (Chinese, Japanese, and Korean) fonts, where fullwidth punctuation is common. This small colon appears in technical standards and certain legacy character sets to provide a proportional alternative to its fullwidth counterpart without altering its basic function of separation or introduction in a sentence.
