How to refer to characters/glyphs not in the document character set
- The SVG Specification uses an element
[AltGlyph](http://www.w3.org/TR/SVG/text.html#AltGlyphElement)
to refer to variant glyphs
- MathML uses an element
[<mglyph>](http://www.w3.org/TR/MathML2/chapter3.html#presm_mglyph)
for "presentation glyphs".
- Unicode has specific and generic Variation Selectors
(U+FE00~U+FE0F), see (Unicode Consortium)
[Standardized
Variants](http://www.unicode.org/Public/UNIDATA/StandardizedVariants.html). The usage of these is also discussed in the document [Unicode in XML and other
Markup Languages](http://www.w3.org/TR/unicode-xml/#Format) mentioned above.
Character semantics
- Unicode defines character semantics in the Unicode Character
Database (UCD, available at
[UnicodeData.txt](http://www.unicode.org/Public/UNIDATA/UnicodeData.txt);
here is an explanation of its contents: [
