I am having a problem inputting non-English script in the terminal. Ibus is installed with all necessary packages and is working fine in every application, except the terminal. I cannot even copy and paste Chinese into the terminal. The non-Latin-based characters are displayed as "?".
I do not want to run Chinese shell commands. I only want the terminal to recognise the names of files that have Chinese characters. Two examples are: copying and creating directories with Chinese names; and selecting image files with feh when configuring Openbox. Basic stuff like that. So it is not necessary to enable direct input of non-Western characters. I would be happy if I could paste Chinese characters into the terminal.
I have experimented with terminal and system configurations, but cannot figure out how to do it.

Is your locale set to UTF-8 in your config(usually something like /etc/profile.d/lang.sh)?
What terminal do you use? Does it support unicode?

Yes, my Chinese locale is set to UTF-8.
As for inicode, I believe it is one of the default settings with Debian, but I am not sure. It has been a while since I have configured anything that has unicode as an option. And to be honest, my brain is so muddled from work at the moment, I cannot think of where to look for unicode settings.
I usually use the root terminal, with Debian 6 Stable. Although Ibus does not work with the simple word processor (Mousepad), I can still paste non-European writing. Only the terminal has a problem with displaying Chinese.

Is that a terminal emulator? I mean a terminal emulator such as rxvt, aterm, xterm, eterm, konsole etc. Some of them have unicode versions, such as uxterm or urxvt.

Debian's documentation describes XFCE's terminal as a lightweight and easy to use terminal emulator for X11. "Comparable to GNOME 2 terminal."
I am a beginner with the terminal. Judging from my limited experience, I thought the difference was root terminal with full root privileges and terminal emulators without full privilege, because only root terminal gives me complete access.
If XFCE has an emulator, is it possible to configure it the way I want or is an emulator limited to Latin-based text?
Yes, I am a shell command beginner. Since, apparently, I seem confused about the difference between a regular terminal and an emulator, I am not experienced enough to be considered even a novice.
