Not exactly.  I am saying that the various i18n patches were an utter failure
for me.  I use the par out of MacPorts, and the key patch is this:

--- ./par.c.orig        2001-04-01 23:25:57.000000000 -0500
+++ ./par.c     2012-04-15 13:56:42.000000000 -0500

+      // Exclude non-breaking space from the class of space chars
+      if (isspace(c) && isascii(c)) ch = ' ';
       else blank = 0;
       additem(cbuf, &ch, errmsg);
       if (*errmsg) goto rlcleanup;

Your problem is probably the same one I ran into; isspace() would interpret
0xA0 as a non-breaking space and replace it with a "real" space, messing
up UTF-8 sequences.

This isn't perfect; in a perfect world you'd pull in the bytes and call
wcwidth() on each Unicode character, but it works good enough for me in
