How to define/calculate the *weight* in your context?

It makes the behavior more logical, but it doesn't fix > existing scripts. We find that the $LANG will affect how glibc deal with the wildcard. We all test on LANG=en_US.UTF=8, but if I set export LANG=C, then [a-z] and [A-Z] are all as expected, and xfstests make install works.
