Bug #53891 [NEW]: iconv_mime_encode() fails converting UTF-8 string to quoted-printable

From: Operating system: GNU/linux (gentoo/kernel 2.6.35) PHP version: 5.3.5 Package: Mail related Bug Type: Bug Bug description:iconv_mime_encode() fails converting UTF-8 string to quoted-printable Description: ------------ iconv_mime_encode() fails on certain UTF-8 strings containing at least one multibyte character. The error is reproducable for these strings. I have further noticed that it is more likely that this error occurs if a multibyte character is found at the following character positions within the string: 24±1, 52±3, 82±4, 112±5, 143±5 The code that led me to the previous conclusion can be found here: http://pastebin.com/GXQZ129M Test script: --------------- $preferences = array( 'scheme' => 'Q', 'input-charset' => 'utf-8', 'output-charset' => 'utf-8', 'line-length' => 74, 'line-break-chars' => "\r\n", ); // Note the ellipsis character at the end of the following string: iconv_mime_encode('subject', "d obeybiubrsfqllpdtpge…", $preferences); Actual result: -------------- PHP Notice: iconv_mime_encode(): Unknown error (7) in /home/soulmerge/test.php on line 11 Notice: iconv_mime_encode(): Unknown error (7) in /home/soulmerge/test.php on line 11 -- Edit bug report at http://bugs.php.net/bug.php?id=53891&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53891&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53891&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53891&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53891&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53891&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53891&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53891&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53891&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53891&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53891&r=support Expected behavior: http://bugs.php.net/fix.php?id=53891&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53891&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53891&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53891&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53891&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53891&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53891&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53891&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53891&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53891&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53891&r=mysqlcfg
