This is one of the things that doesn't worry me much, because if the
application takes care to write the entire UTF-8 character at once, it
will enter the clist in the proper order, except when:
- the TTY hits its watermarks during the write
- traffic enters the TTY inwards, which has to be echoed (even though
this will probably be caught by locking as well), while an UTF-8
character is entering the TTY outwards.
