And yes, there will be some characters that don't have No - in fact in English it is basically OK but in other languages it is not.

Do you want the question is RPM name A == RPM name B to depend upon locale ? Isn't that a bit of a hazard - imagine if you have multiple respositories and your dependancies pulled a different package in German to English locales ? > There's nothing particularly special about rules that say character > numbers so-and-so are equivalent to character numbers so-and-so, in > sections throughout the repertoire, with other blocks of characters that There is a lot special. The rules for caseless comparison of the unicode character set, case conversion and the like are huge. Some languages don't have such a concept, some differ on how they are compared. The comparison of accented and non-accented character variants is also a big deal that Americanglish doesn't have to deal with but the rest of the world does. Even apparently simple things like German throw in some absolute gems. Try for example ß which has no upper case ligature but translates into a pair of 'S'. Then the fun starts - how do you determine if any given pair of SS ligatures in German are the same as ß if lower cased. Greek has position dependant casing while in Turkish the letter I is a whole little bomb of its own. > don't have equivalents. Unicode just extends the size of the > repertoire. And the rule set, and the number of case forms (upper, low and title) - see upper/lower isn't really enough. Welcome to planet Earth as seen by the rest of us At this point you hopefully start to see why "Did you mean XYZ" is much easier to implement, and also more useful ! There are very very good reasons to keep "is RPM name A the same as RPM name B" a question that is not dependant upon anything else. Case is a concept that doesn't have that property.
