For the first part, you want LC_NUMERIC=C. For the second part, what you're asking for is sometimes called "rational ranges", or "rational range interpretation". This is the notion that, for specific range expressions like '[a-z]' within a regular expression or glob, the software will assume you want to match only '[[:lower:]]', rather than doing what you actually said. The idea behind this is based on the (probably accurate) belief that most people who write [a-z] or [A-Z] in their scripts wanted the LC_COLLATE=C (or 1980s) meaning of the range, not the meaning of the range in modern times. Thus, it's a sort of safety net strung below the novice programmer, to catch them when they fall. Since this is not how systems currently behave, however, what you need to do in your script is write the expression correctly. For your example, I believe that would be [[:xdigit:]]. Or if you really do mean to restrict it to lower-case 'a' through 'f', retain what you have, but set LC_COLLATE=C first. I haven't seen rational range interpretation discussion that covers '[a-f]', but I haven't been following it closely.
