Re: display undeclared iso-charset in UTF environment

    Assuming that unlabelled articles are in Latin-9 seems not a good
choice. Experience shows that, for westerners, the vast majority of such
articles really are in CP-1252 or Latin-1. A small minority is in UTF-8.
And peanuts for all other charsets, including Latin-9.

    So, for westerners, the best choice is probably either a fixed
CP-1252, or some auto-sensing between UTF-8 and CP-1252 (I mean a
Vim-like fileencodings="ucs-bom:utf-8:latin1").

    Then there are other populations, and a Chinese or Polish guy
probably prefers some other default charset (or auto-sensing list).
Should be configurable.

    I don't understand the interest of grepping specifically those
chars. Why not just convert all unlabelled articles? Or grep for any
char above 0x80?

    Is there no better way to get current CODESET then parsing env vars?
It seems to me you get parsing reversed: The active value is LC_ALL if
defined, otherwise LC_CTYPE, otherwise LANG. Finally, once you have the
current CODESET, why limit the fixing to UTF-8? It could be also usefull
in other locales.

| bash: /sw/bin/iconv: No such file or directory

    BTW you could simply remove "-t UTF-8" so iconv itself converts to
the current locale's charset.
