x01F28

x01F28 commonly refers to the hexadecimal notation for the Unicode code point U+01F28. In many contexts, a leading x or 0x denotes hexadecimal values, while Unicode code points are typically written with the U+ prefix. When interpreted as U+01F28, the value designates a single character within the Unicode standard.

U+01F28 is located in the Greek Extended block, which runs from U+01F00 to U+01FFF. This block is used for polytonic Greek letters, diacritics, and related characters that extend the classical Greek repertoire. The exact glyph, official name, and typographic properties of U+01F28 are defined in the Unicode Character Database, and may vary depending on the font and rendering system in use.

Rendering of the character depends on font support and text rendering engines. Some fonts provide a glyph for U+01F28, while others may render a missing-glyph symbol. In programming and data contexts, treating x01F28 as U+01F28 requires correct text encoding; misinterpretation can occur if the value is not properly decoded or if a non-Unicode encoding is assumed.

Common uses of such code points include scholarly texts, linguistics, and digital typography that require historically accurate Greek letters or diacritics. For researchers and developers, the recommended approach is to consult the Unicode charts and the Unicode Data files to confirm the character’s official name, general category, and rendering guidance, and to test display across fonts.
