How to refer to characters/glyphs not in the document character set

• The SVG Specification uses an element AltGlyph to refer to variant glyphs
• MathML uses an element <mglyph> for "presentation glyphs".
• Unicode has specific and generic Variation Selectors (U+FE00~U+FE0F), see (Unicode Consortium) Standardized Variants. The usage of these is also discussed in the document Unicode in XML and other Markup Languages mentioned above.

Character semantics

• Unicode defines character semantics in the Unicode Character Database (UCD, available at UnicodeData.txt; here is an explanation of its contents: Unicode Data File Format, see also: (Unicode Consortium, UTR Draft) Unicode Technical Report #23 CHARACTER Properties
• (Unicode Consortium, TUS Annex 21) Case Mappings
• (Unicode Consortium, UTR Draft) Unicode Technical Report #30 Character Foldings
