As far as I know, any coding system set in
locale-coding-system is stateless.  None of them uses escape
sequences.  So, decoding and encoding should yield the same
value.  If that is uncertain, we can put the original
unibyte string as a text property (say, `encoded-string') to
each of decoded string.

User programs?  Then, what to do with M-x setenv?
