Thanks a lot for the "%!"-idea! That's what I needed.

This works:
:set fencs=utf8
:%!cat
although "fenc" remains "latin1".

It is not appropriate to use "iconv -f latin1 -t utf8" (that does in
fact corrupt the data!) because the data is already in UTF-8, and that
is why it is not displayed properly in Vim (because Vim thinks it is
in Latin-1); in particular, the short dash character is shown as
"â<80><90>". When it is displayed properly, a "‐" is shown; putting
the cursor at it and doing "ga" reports that this is character number
0x2010.

Why does "set fencs=utf8" matter for the "%!cat" operation if Vim is
not going to change the "fenc" accordingly?

Cheers,
Albert.
