Package pyxb :: Package utils :: Module unicode

Module unicode

This module contains support for Unicode characters as required to support the regular expression syntax defined in annex F of the XML Schema definition.

In particular, we need to be able to identify character properties and block escapes, as defined in F.1.1, by name.

Block data: http://www.unicode.org/Public/3.1-Update/Blocks-4.txt
Property list data: http://www.unicode.org/Public/3.1-Update/PropList-3.1.0.txt
Full dataset: http://www.unicode.org/Public/3.1-Update/UnicodeData-3.1.0.txt

The Unicode database active at the time XML Schema 1.0 was defined is archived at http://www.unicode.org/Public/3.1-Update/UnicodeCharacterDatabase-3.1.0.html, and refers to Unicode Standard Annex #27: Unicode 3.1.
