Bug #10489: quoted_printable_decode() & imap_qprint() decodes control codes.

From: slaygon@NOSPAMcensor.net Operating system: Linux 2.4.3 PHP version: 4.0.4pl1 PHP Bug Type: *Mail Related Bug description: quoted_printable_decode() & imap_qprint() decodes control codes. quoted_printable_decode() and imap_qprint() decodes control codes aswell. This, I assume, is not supposed to happen. Also, these functions happily translate anything with two characters after the = sign (like =EV in =EVIL), which they shouldn't. Example: $foo="This is =00=01 =E4 \"=20\" =21 =ev =FE string."; echo "Quoting string \"".$foo."\"\n"; echo "quoted_printable_decode: \"".quoted_printable_decode($foo)."\"\n"; echo "preg_replace: \"".preg_replace("/\=([2-9A-Fa-f])([0-9A-Fa-f])/e", "''.chr(hexdec('\\1\\2')).''", $foo)."\"\n"; Would result in: Quoting string "This is =00=01 =E4 =2B "=20" =21 =ev =FE string." quoted_printable_decode: "This is ä + " " ! ï þ string." preg_replace: "This is =00=01 ä + " " ! =ev þ string." Am I wrong in assuming that quoted_printable_decode() and imap_qprint() should act as my preg_replace line above does? -- Edit Bug report at: http://bugs.php.net/?id=10489&edit=1
