Then that's the problem.  xterm uses the locale, but does not set it.
The "uxterm" script sets the locale before invoking xterm.

The xterm manpage gives a list of variables which it may set.
For instance:

       XTERM_LOCALE
            shows the locale which was used by xterm on startup.  Some shell
            initialization scripts may set a different locale.
