According to POSIX, [a-z] is undefined in locales other than C or POSIX. This isn't a recent change. POSIX pretty much says that you need to use [[:lower:]] instead. I don't doubt that a lot of code doesn't follow these rules, and saying that it is broken according to POSIX doesn't help users who run into issues. But on the glibc side, I don't see anyone else arguing that this needs to be fixed in glibc. -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
