.Sh COMPATIBILITY

Historically, the

.Nm wc

utility was documented to define a word as a ``maximal string of

characters delimited by <space>, <tab> or <newline> characters''.

The implementation, however, didn't handle non-printing characters

correctly so that `` ^D^E '' counted as 6 spaces, while ``foo^D^Ebar''

counted as 8 characters.

4BSD systems after 4.3BSD modified the implementation to be consistent

with the documentation.

This implementation defines a ``word'' in terms of the

.Xr isspace 3

function, as required by

.St -p1003.2-92 .
