Ubuntu :: Xvfb And CutyCapt - Chinese Symbols Not Recognized

I use Linux * 2.6.18-164.10.1.el5.028stab067.4ent #1 SMP Fri Jan 15 03:06:15 MSK 2010 i686 build to configure xvfb + cutycapt, I need it to convert html to image. The package that I have already installed:

build-essential
xvfb
xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic
libgl1-mesa-dri
libqt4-webkit libqt4-dev g++
x11-xkb-utils
xserver-xorg-core

It seems like it works, but there is one problem. It misses chinese symbols when converts html to image. I thought that it is encoding issue and rechecked all my conf related that and set default encoding up to es_US.UTF8.

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I'm testing these on the 2 computer. local and my vds. They both have Ubuntu 10.04. On the local machine all works fine, but on the vds it doesn't take chinese symbols. Where can I find the difference between machines configurations? I suspect it depends with X server configuration.
