After reviewing the documentation of Unicode case matching, I think those proposing "full" Unicode case matching for CSS user identifiers are underestimating both the complexity of the implementation along with it's utility. The discussion at TPAC by the Internationalization WG concluded that CSS should use full case matching for user-defined identifiers but I don't see much discussion of the actual case matching algorithm to be used. I think the complexity involved actually requires careful consideration and I've posted on www-international stating the reasons. [1], [2] I think the comment by Anne van Kesteren is most apt, for the problem at hand full Unicode case mapping is overkill. [3] Steve Zilles summed this viewpoint up quite nicely during the telcon discussion last week [4]: > SteveZ: No strong opinions, but anne's solution more likely to be > interoperable. Trying to track bugs for edge cases is bigger > pain than the value of being insensitive, and interop would suffer If ASCII case sensitivity is seen as an inappropriate to use for user-defined identifiers, I think we should stick with case sensitive matching instead. We should only opt for full Unicode case matching if someone can desribe in detail the exact case matching algorithm and justify why the complexity involved is worth the trouble.
