The odd screenshots look like the application is using UTF-8 encoding
while the terminal is not setup for that.  Eterm and aterm don't support
UTF-8, I recall.  xterm and urxvt do support it.

Your example script uses UTF-8 encoding.  If the locale were set properly
for each terminal, it would be possible for instance to use recode to
generate a ISO-8859-1 encoded version of the script for Eterm and aterm.

It would be possible to modify dialog so that it did the recoding - but
that's not currently implemented.
