Hi Mathieu,

Thanks for figuring this out! Instead of the unit length bytevector with
an 'e' character, can we just use a unit length bytevector with the null
character? That would be less surprising to the reader. WDYT? See
attached patch.

Regards,
Arun

Subject: [PATCH] email: Do not use an empty bytevector to test the charset.

Using an empty bytevector no longer throws an exception since Guile
commit 5ea8c69e9153a970952bf6f0b32c4fad6a28e839.

* email/email.scm (post-process-content-transfer-encoding): Use a
bytevector of unit length to test the charset validity.
