Asunto: [SM-DEVEL] Bug in mime.php:decodeHeader()
De: Christian Schmidt <christian@ostenfeld.dk>
Fecha: S?b, 23 de Marzo de 2002, 14:48

Currently, the decodeHeader decodes headers containing several
encoded-words incorrectly. E.g. the header "=?iso-8859-1?Q?=C9?= and
=?iso-8859-1?Q?=E9?=" is decoded into "? and ?" and not into "? and ?"
as expected.

Also, it currently does not ignore white-space between consecutive
encoded-words as it should.
