As long as you do not change the encoding twice, the harm is not so big: You
see the wrong character on screen but the file will not be changed.

You are right (and this can easily be done).

I wonder whether the recode program/library could be used. It is mature
and comprehensive and exists on Unix, Mac and DOS (don't know about VMS).
It also implements several modi on how to deal with non-transferable
characters.

Also, the recode API could serve as model (in some kind of view, e.g. for
charcode names) and its documentation (info: recode) gives a good
introduction into the charset problematic.
