Unexpected result for iconv_mime_decode

[cedric-anne]

Description

The following code:

<?php
echo(iconv_mime_decode('=?windows-1258?Q?DSI_Charg=E9_de_Formation_Jean_Dupont?= <jdupont@example.fr>', ICONV_MIME_DECODE_STRICT, 'UTF-8'));

Resulted in this output:

DSI Chargé de Formation Jean Dupon <jdupont@example.fr>t

But I expected this output instead:

DSI Chargé de Formation Jean Dupont <jdupont@example.fr>

Nota:
On PHP 7.2.34, result is different, but still buggy.

DSI Chargé de Formation Jean Dupon <jdupont@example.fr>

PHP Version

8.1.0

Operating System

Ubuntu 20.04.1

Result is the same with PHP 7.4.27 and 8.0.15.

Indeed, the fix for bug 79200 wasn't quite right regarding iconv_mime_decode().
