Some x-terminals do not compose unicode characters

["Alessandro T." <tagliare3@yahoo.it>]

Hi,
I would get the strikethrough text in x-terminal-emulator. So I tried

echo -e '1\u0336'

and with mlterm, pterm, rxvt and xterm I got, rightly, strikethrough 1.
Instead with evilvte, gnome-terminal, lilyterm, lxterminal, sakura,
terminator, terminix, termit, vala-terminal and xfce4-terminal (my
default) I got 1-.

This is caused by incorrect configuration? So where should I intervene?
Or is it a bug? So what package should I report?

Thanks
