If for lower->upper replacing inside ASCII only, "LC_ALL=C tr [a-z] [A-Z]" is most portable because some tr implementations even not understand [:class:] but some other have SysV-ism to specify ranges in the [], against what POSIX says. But I think that "LC_ALL=C tr a-z A-Z" is better middle point here because not teach user to incorrect syntax from the scripts.
