Encoding and character set are not mixed up in the definition, but the 
confusion of the submitter of the bug reminds me of the discussion we had 
on the definition of text (see the clarification for the definition of text 
at http://lists.w3.org/Archives/Public/w3c-wai-gl/2005JulSep/0135.html).

We could redefine non-text content as:

    Content that is not represented by a character included in the 
<http://www.w3.org/TR/2005/WD-WCAG20-20050630/#unicodedef>Unicode / ISO/IEC 
106464 repertoire
    or (by) a sequence of characters included in the 
<http://www.w3.org/TR/2005/WD-WCAG20-20050630/#unicodedef>Unicode / ISO/IEC 
106464 repertoire.

This would make the wording consistent with the definition of text.

Christophe Strobbe
