There are a couple of things to consider here.
1. Bash doesn't have a "built-in" regexp engine. It uses whatever POSIX-
compatible regexp API the C library provides.
2. POSIX range expressions are explicitly non-portable and locale-
dependent. The characters in a range depend on the locale's collation
sequence. Look back at this list for discussions of how upper and
lower case letters get into a range like a-z.
