More reliable, yes; in fact, this is what autoconf uses under the hood for constructs like AS_TR_SH. But POSIX requires tr and sed to understand [:upper:] and [:lower:], and to understand it in the context of the current locale (there are some locales where blindly using the 26 letters of English is the wrong behavior, and where you really do mean [:upper:]). - -- Life is short - so eat dessert first!
