Re: CHARACTER_ENCODING_SUPPORT and Accessibility: document scope

Thanks for this input on this. It is a problem as I can attest to as I
live in Spain and I'm accustommed to seeing triangles, question marks
and hash signs in the middle of words, even on bank statements and
official letters. I expect that users with completely different
character sets like Korean (or vice versa) can end up seeing nothing
at all. And this is more of a problem for some users than for others.

However, the document is about encouraging people who have adopted one
set of guidelines or best practices to understand what is involved in
taking on the other. In this case, that means that we need to say
"You've already adopted CHARACTER_ENCODING_SUPPORT, look what can now
do to comply with WCAG". This would seem to go with WCAG 1.0
checkpoint 11.3, "Provide information so that users may receive
documents according to their preferences (e.g., language, content
type, etc.)" but there's no mention of character encoding and I don't
think it's something people have traditionally worried about. In WCAG
2.0 I don't even see content negotiation or character encoding
mentioned. So having complied with CHARACTER_ENCODING_SUPPORT doesn't
actually help with WCAG compliance.

So although it's something people *should* do to help accessibility,
it isn't actually required by any checkpoint. It's something for the
WCAG WG to look into.

cheers,

Alan

This means that all your efforts to be WCAG compliant, with all your quick access to assistance, guidance, explanations and other pointers that your users expect to observe, could be completely undermined. You could leave vulnerable end users with nothing whatsoever, except perhaps a feeling that they (and not you) have done something wrong. Plus, the one site from where they might expect to get help regarding access to your content/service is the one site that is now inaccessible to them. Anyone who has gone to the effort of being WCAG compliant should be concerned about loss of accessibility due to encoding mis-matches.

We've already seen how many browsers now present security status in this way (the padlock icon or the coloured address bar) so why can't some accessibility features be there too. Like a "panic button" when some dumb-*ss gives you encoding your browser can't handle?
