I'm sliding over the details of what you said because they're irrelevant for my purposes. All I need is a consistent/transitive comparison, which I think is a reasonable expectation. Again, jumping straight to the point: > The best you can do with NSString *only* is to assume that words like "laßt" > are just mis-spelled English words (if your locale is us_EN).

I don't care where "laßt" is placed in the sort order for "en_US" (or any other locale), just that it has a single consistent location (so long as the same locale is always used for all comparisons). > 3.

Markus found no transitivity > failure for de_AT; I found no transitivity failure for us_EN in 10.7.3, > though you reported you did; That's correct- I reproduced that the comparison is not transitive for some strings with an eszett character on 10.6.8 and 10.7.3 with the "en_US" locale. I have since noticed that the project's base and deployment SDK are set to 10.6, so perhaps the bug only manifests because the frameworks are providing compatibility. > Maybe give 'localizedStandardCompare:' a try? Thank you for the idea, but that won't be suitable for me because I need to be able to specify the locale. Well, I'll try bumping the base SDK to 10.7. If I can still reproduce the issue after that, I'll file a radar. ~Martin _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
