wc -mlw report1 report2
wide-character equivalent of the isspace()
tests whether widec
is a wide character belonging
to the wide character class "space".
class "space" is disjoint from the wide character class "graph" and therefore also disjoint from its subclasses "alnum", "alpha", "upper", "lower", "digit", "xdigit", "punct".
contains the wide character class "blank".
Always contains at least the space character and the control characters \f
, \n
, \r
, \t
, \v
.
Depends on the LC_CTYPE
category of the current locale.
