[dev] [tabbed] utf8 characters not displayed in tabs

[Seb]

hi,
I am using xterm under tabbed (v.0.6) and some of the polish characters which are 
in the directory name are not displayed in the tabs and the rest of the name is 
truncated, for instance:

/home/seb/żółty is truncated to /home/seb/żó

when I set the Xresource :

*XTerm*utf8Title: True

then the whole name is displayed with all polish characters but only after I 
change directory to a new location, so the name in tab does not refer to actual 
directory.
