That's the same issue as [0-9] not matching =EF=BC=99. > I already can't understand the new rules ... The range operator matches characters according to their collation weight, and sincce the weight of 'a' is less than the weight of 'A', 'a' is not included in the [A-Z] range. This could be fixed by including all characters with the same primary weight as the endpoints (so that [=C4=81-=E1=BA=91] and [a-z] would end u= p being the same). It makes the behavior more logical, but it doesn't fix existing scripts.
