I agree, this is probably a common case. The patched code does include
a check to see if the multibyte string can be displayed in the current
execution environment. If it cannot then the code falls back on the old
behaviour of displaying the multibyte characters as a sequence of

Evaluated: yes. Been able to do anything about it: no. It is really up
to the system administrator where the tools are being used to make sure
that they were compiled with the correct character set settings, and
that these settings are then used when the tools are used.
