Yeah, the idea of a helper function I agree with; I am not thrilled
with the name utf8_fprintf() though.  People use the return value of
fprintf() for error detection (negative return value means an error)
most of the time (even though non-negative value gives the number of
bytes shown), but the primary use of the return value from the
utf8_fprintf() function will be to get the display width, and the
name does not quite capture that.
