]

counts lines, words, runes, syntactically-invalid

A word is a maximal string of characters
delimited by spaces, tabs or newlines.
The count of runes includes invalid codes.

.SH BUGS
The Unicode Standard has many blank characters scattered through it,
but
.I wc
looks for only
.SM ASCII
space, tab and newline.
.PP
.I Wc
should have options to count suboptimal
.SM UTF
codes
and bytes that cannot occur in any
.SM UTF
code.
