Right. This bug (the TRANSLATE command does not work correctly on machines
with Little Endian architecture) will be fixed in the next release.

This is indeed a bug. Since 7-bit character sets such as the national
versions of ISO 646 do not contain any 8-bit characters, then any 8-bit
character in the source set should be translated to "?", rather than having
its 8th bit stripped. This will be fixed in the next release.

This is a reasonable request; I'll add it to the long, long, long list.
By the way, the C-Kermit 7.0 bug list is here:
