I see the same problem with Norwegian characters.  The UTF-8 bytes are
shown as ISO-8859 characters and not as the characters I expect.  To
allow you to test this, I added the norwegian characters in the
subject.  I use this on a machine with LC_CTYPE=nb_NO and 'locale
charmap' returning ISO-8859-1.

Here is another copy: æøåÆØÅ

This should show 3 lower case letters and 3 upper case letters, one
'ae' combination, one o with a slash from lower left to upper right,
and finally the letter a with a small ring above it.

(Hm, now I hope the characters are encoded as UTF-8.  Time will
tell. :)

Happy hacking,
