no-break spaces instead of spaces, except directly after a comma.

 Determines and returns the number of column positions required for @var{uc}.
 Returns -1 if @var{uc} is a control character that has an influence on the
 column position when output.

 Determines and returns the number of column positions required for first
 @var{n} units (or fewer if @var{s} ends before this) in @var{s}.  This
 function ignores control characters in the string.
