Mapping of Unicode Characters - Private Use Characters - Vendor Use

Vendor Use

  • The Adobe Glyph List uses the PUA for some of its glyphs.
  • Apple lists a range of 1,280 characters in its developer documentation of U+F400–U+F8FF within the PUA for Apple’s use. Of those, only 311 are used in the range U+F700–U+F8FF.
  • WGL4 uses the PUA (U+F001 and U+F002) to encode two characters which are duplicates of the ligatures fi (U+FB01) fl (U+FB02).
  • In old versions of its RichEdit component, Microsoft mapped U+F020–U+F0FF within the PUA to symbol fonts. For any character in this range, RichEdit would show a character from a symbol font instead of the end-user-defined character (EUDC).
  • AutoCAD uses U+F8FC–U+F8FE for ⌀ (diameter sign), ± (plus-minus sign) and ° (degree sign) respectively.
