 GRASS fails even start on Windows when username contains non-ascii
 characters

 When I change line source:grass/trunk/lib/init/grass.py#L620

 {{{
             os.environ['MANPATH'] = to_text_string(addons_man_path)
 }}}

 to

 {{{
             os.environ['MANPATH'] = addons_man_path
 }}}

 then GRASS starts and even MANPATH variable is set up correctly (including
 non-ascii characters). Function `to_text_string` is apparently buggy.
 Tested on Czech (cp1250) Windows 8.1.
