The iissuuppppeerr() function tests for any upper¡case letter or any of an im¡
plementation¡defined set of characters for which none of iscntrl(3),
isdigit(3), ispunct(3), or isspace(3) is true. In the _`_`_C_'_' locale,
iissuuppppeerr() returns true only for the characters defined as upper¡case let¡
ters.
