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.
