urxvt: input method problem

[kyanh]

Hello all,

`xvnkb` is a vietnamese keyboard and it currently works well on any GTK applications. It uses below settings in `$HOME/.bashrc`:

/=================
| export GTK_IM_MODULE=xim
| export LD_PRELOAD=/usr/local/lib/xvnkb.so.0.2.9
\=================

But I cannot type any vietnamese in `urxvt`. I donnot how to get debug messages. I just know that I can type vietnamese easily with `urxvt` on my former Arch Linux.

Thank you very much for your helps.

Regards,
