U1F23

U+1F23 is a Unicode code point located in the Greek Extended block, which spans U+1F00 to U+1FFF. The character represented by this code point is a Greek letter with diacritical marks, used in polytonic Greek notation and scholarly editions. As with other characters in this block, the exact glyph is determined by the font rendering the text, so appearance can vary across typefaces.

Encoding and representation: U+1F23 is a single code point in the Unicode repertoire. Because it lies within the Basic Multilingual Plane, it is represented in UTF-16 by one 16-bit unit and in UTF-32 by one 32-bit unit. In UTF-8, it requires three bytes. In digital texts, it can appear either as the precomposed character (if the font supports it) or as a base Greek letter combined with one or more diacritic marks in a decomposed form.

Usage and rendering: The code point is primarily relevant to scholars working with ancient or classical Greek texts that employ diacritics such as breathing marks and accents. In environments lacking support for this specific precomposed character, rendering may fall back to a combination of the base letter and combining diacritical marks. Proper display depends on both Unicode data conformance and font coverage.

History and standards: U+1F23 is part of the Unicode Standard’s efforts to encode polytonic Greek with diacritics. The character’s official name and properties are defined in the Unicode Character Database and accompanying documentation. The block and code point are regularly referenced in update notes for Unicode releases.
