+Remember that ranges within a bracket expression of a regular expression

+Meanwhile, support for character classes like @samp{[[:upper:]]} is not

+as MacOS X 10.5 where not all 8-bit byte values are valid characters,
+even though that platform has a single-byte @samp{C} locale.  And Posix
+allows the existence of a multi-byte @samp{C} locale, although that does
