I guess that emacs will have a problem if you have stuff with
different encodings in one file.  AFAIK there can be only one encoding
per file.  At least, if there are characters which are not supported
by the current encoding you'll be asked which encoding should be used
when saving the file.

However,  you can switch between input encodings (without much care)
if you split the document into different files and set \inputencoding
at the top of each file.

Coming back to the original question, I think your hint is quite
useful.  If you have to insert some text with an unknown encoding it
is quite safe to put it into a separate file and use \input to
integrate it into the document.  You don't have to be careful at all
when you try \inputencoding with different arguments because a wrong
value does not break anything.  If the encoding is unknown, you can
try all encodings supported by LaTeX until you find one which works
properly.

If the encoding of stuff pasted into emacs from another file, which
encoding is unknown, I suppose that if you switch to fundamental-mode
the file is treated as a binary and it is saved as it is.
