unescape

public String unescape(String s,

Unescapes escaped characters in the specified string, according to the CSS specification. This could be done directly in the parser, but portions of the lexer would have to be moved to the parser, meaning that the grammar would no longer match the standard grammar specified by the W3C. This would make the parser and lexer much less maintainable.
