I little thought and an experiment later, and I discovered:
When you edit a line with the kernel's terminal line editor, when you press the Delete key, it writes backspace-space-backspace and removes one byte from the input. That fails to do the right thing on UTF-8 terminals.
For example, in a UTF-8 xterm or Gnome terminal, or even on the Linux console after running "unicode_start", run the command "cat" by itself, then type "ééé", then hit DEL twice - it will show one accented letter(*). Press enter, and cat will echo the line containing _two_ letters.
There is no fancy environment setting which corrects this problem. The kernel needs to know it's dealing with a UTF-8 terminal for basic line editing to work.
(*) The text in quotes is three E WITH ACUTE letters, in case that doesn't show properly in your mailer.
