1157Seems to be a known bug, read
1158L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
1159following ugly workaround to get non-double-wide-characters working:

1201=head3 Character widths are not correct.
1202
1203urxvt uses the system wcwidth function to know the information about
1204the width of characters, so on systems with incorrect locale data you
1205will likely get bad results. Two notorious examples are Solaris 9,
1206where single-width characters like U+2514 are reported as double-width,
1207and Darwin 8, where combining chars are reported having width 1.
1208
1209The solution is to upgrade your system or switch to a better one. A
1210possibly working workaround is to use a wcwidth implementation like
