This function ignores any encoded-word specified in a character set not supported by the mbstring extension (e.g. Arabic windows-1256). Such encoded-words pass straight through.

RFC2047 doesn't specify the behaviour, but common agents such as Gmail, Windows Mail, etc. DO NOT ignore such encoded words. They are decoded as if they were declared to be in the local character set.

Be aware of this idiosyncrasy.

See also the following functions which may work better in some cases:
iconv_mime_decode() - http://php.net/manual/function.iconv-mime-decode.php
imap_utf8() - http://php.net/manual/function.imap-utf8.php

In Q encoding mode, RFC 2047 encodes spaces as _ (Section 4.2). 

mb_decode_mimeheader()

does not appear to do this. Thus, to avoid names or subjects with underscores, one needs to apply strtr() or similar function to the input string.

On the other hand, lower-case strings do now work correctly.

Using quoted-printable-encoding the hex-numbers must be written in uppercase letters!

Works: =?iso-8859-1?q?=3F=3F=3F?=
Fails: =?iso-8859-1?q?=3f=3f=3f?=
