I also don't understand the problem you explain.  Some questions:

  - Does it happen with unicode only or also with ascii?

  - Does it happen using TrueType or bitmap fonts?

  - As TrueType, do you use DejaVu Sans Mono?

  - Have you tried to reproduce the bug with another window manager?
    I remember many times, occasionally, and this is not recent, to
    notice strange behaviors with xterm in fvwm2, I never stopped to
    investigate why.

  - Do you use custom settings in ~/.Xdefaults or ~/.fonts.conf?

  - Which graphics do you use?  Does it happen with other machines?

I think the resize screen Kirill mentions is another issue.
