[Message part 1 (text/plain, inline)]

Running the following lisp code:

    (mail-header-parse-address "Łukasz Stelmach <steelman <at> post.pl>")

yields the error message:

    Unknown symbol: Ł

and the invalid result:

    ("steelman <at> post.pl" . "ukasz Stelmach")

As far as I can tell this happens if the first character of the address
string is an UTF-8 (non-ascii?) one.

Why are you using that function?  It assumes the non-ASCII characters
were rfc2047-encoded.

I suggest to use mail-extract-address-components instead.

It's not me using it but Gnus in gnus-summary-limit-to-author and a few
other places. I receive the "Unknown symbol" when signing with gnupg,
too.

Then please show a recipe using Gnus to read or send messages that
fails due to this, then the Gnus maintainers will be able to look into
that.  Please don't assume the problem is with this particular
function, the actual problem might be elsewhere.

Thanks.

OK. Should I file another bug or "rename" this one?

This has been fixed in later versions of Emacs.

On (nearly) current master I don't get an error but this:

("steelman <at> post.pl" . "ukasz Stelmach")

Is that correct?

No need to file a new bug, you can use this one.  Bonus points for
using "retitle" to make the title more accurate and mentioning Gnus.
See admin/note/bugtracker for how to use "retitle".

Thanks.

Yes.  It's a function meant to be used to parse RFC2822 addresses, and
that's not a valid input.
