>From your last link, see answer #3 (about wcwidth/wcswidth which are POSIX).

Citation from there:
The size of the string as it appears on the screen is unrelated to the number 
of code points in the string. One has to communicate with the rendering engine 
for this. Code points do not occupy one column even in monospace fonts and 
terminals. POSIX takes this into account.

So why are you not using wcwidth() ? You can find code in the src/progress.c 
from wget1.x which you may shamelessly copy&paste as you like (Copyright is 
also by FSF).
