[Trisquel-users] How should I write "ĵ" ?

[pascal]

Hi, I don't know why, but in xterm I can't write "ĵ" or some "ǔ" (no  
characters printed).
>accents like "é" or "ò" works.
my xterm arguments are : -en utf-8 +ulc +sk +samename -pc -bc -bd green -cr  
white -bg black -fg white +j -sb -font  
-misc-fixed-medium-*-*-*-14-*-*-*-*-*-iso10646-*

and my xterm version is XTerm(271).

Thanks in advance.
