2nd reply - I noticed that in this email, the non-ASCII characters
you're using are not UTF-8, but are one of the ISO-8859-x flavors.
That is, 

        'æ' is 0xE6
        'ø' is 0xF8
        'å' is 0xE5

get_wch() in a UTF-8 encoding such as "nb_NO.utf8" will be looking
for UTF-8, which happens to use the same range of codes, but organized
as multiple bytes.  The UTF-8 encoding for the same characters would
look like (in this ISO-8859-1 email...):
