It seems like a couple emails you are sending are using a normal character
set, but my pine says:
-=-=-=-=-=-=-=-
    [ Part 1, Text/PLAIN (charset: Unknown "y")  12 lines. ]
    [ Not Shown. Use the "V" command to view or save this part. ]
-=-=-=-=-=-=-=-

(I am able to read the message by clicking "v".)

I looked at the mail with less(1), but I don't see any indication of this
unknown "y" charset. Any ideas of what this means or why this is
happening?

Thanks,
