misrepresent anyone or anything.

For this, can't the caller (info-utils.c) simply do "#undef wcwidth"
after including <wchar.h>?  Though perhaps it might not work with C++.

"not good", I meant.  In addition to the above reasons, the name sounds
that it's leaking the implementation detail, unless it is documented
(e.g. "ENCODING is only used as a hint for performance").
