Previous Comments: ------------------------------------------------------------------------ [2005-03-18 09:13:19] mortoray at ecircle-ag dot com I tried the snapshot and got the same results. What appears to be happening is that the encoders detection of disallowed characters does not include the escape sequences required to do the encoding. That is, as long as the string is 7-bit ASCII no encoding is ever done, even if a MIME escape occurs in the source string, no encoding will be done. >From the reproduction, it is obviously expected that a MIME escape sequence will also be properly encoded. ------------------------------------------------------------------------ [2005-03-17 18:09:26] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2005-03-15 10:30:51] mortoray at ecircle-ag dot com Description: ------------ At least for Q encoding, this function is unsafe and does not encode correctly. Raw characters which appear as RFC2047 sequences are simply left as is. Ex: mb_encode_mimeheader( '=?iso-8859-1?q?this=20is=20some=20text?=' ); returns '=?iso-8859-1?q?this=20is=20some=20text?=' The exact same string, which is obviously not the encoding for the source string. That is, mb_encode_mimeheader does not do any type of escaping. That is, the following condition is not always true: mb_decode_mimeheader( mb_encode_mimeheader( $text ) ) == $text Reproduce code: --------------- $text = '=?iso-8859-1?q?this=20is=20some=20text?='; assert( mb_decode_mimeheader( mb_encode_mimeheader( $text ) ) == $text ); Expected result: ---------------- The decode/encode sequence should always return the original text. Actual result: -------------- Returned result is different than original (that is, the assertion fails). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32311&edit=1
