Hexadecimal Character References Do Not Work in TWiki


XML 1.0:

[66] CharRef ::= '&#' [0-9]+ ';'| '&#x' [0-9a-fA-F]+ ';'

HTML 4.0.1:

5.3.1 Numeric character references

Numeric character references specify the code position of a character in the document character set. Numeric character references may take two forms:

  • The syntax "&#D;", where D is a decimal number, refers to the ISO 10646 decimal character number D.
  • The syntax "&#xH;" or "&#XH;", where H is a hexadecimal number, refers to the ISO 10646 hexadecimal character number H. Hexadecimal numbers in numeric character references are case-insensitive.

Test 1

Letter A using decimal code is A or A.

Test 2

Letter A using hexadecimal code is A or A (the latter is HTML only, not XHTML).


The decimal codes work, the hexadecimals do not. Their ampersand is processed as if it were literal.
