Hello Björn,

I think your expectations for what I18N will recommend may not match what we actually recommend :-).

I agree that user stories are important, although the languages most affected are also the ones that it is hardest for us to gather evidence from. It is also true that people have "gotten around" things not working by using ASCII-only identifiers, for example. The advent of more active or actively-generated content and better Unicode support, though, expose us to more problems in this area.

I believe that it is essential that the I18N WG's recommendations should be in harmony with what W3C Specs (and Web technologies) actually do rather than recommending something that is not generally accepted. I believe that these recommendations should then be embodied in a revision of CharMod-Norm. The I18N WG feels that this should include some normalization in selected cases.

Personally, I am looking to the TAG finding to help provide closure on this issue. If we do nothing prior to the advent of HTML5 and CSS3, I feel (others do not) we are making a de facto decision that will be very difficult to change later. I would rather the decision be one taken deliberately.
