I'm not sure how long xemacs will survive (the last stable release of
xemacs was released in 2009). Anyway, I'm not too worried about your
points, since it's easy to convert back from mule-internal code
encoded log files to original encoding mixed log file. No information
will be lost. Even converting to UTF-8 should be possible. My point
is, once the log file is converted to UTF-8, there's no way to convert
back to original encoding log file.
Probably we treat mule-internal encoded log files as an internal
format, and have a utility which does conversion from mule-internal to
UTF-8.
