It looks like this: &BCAEMARBBEEESwQ7BDoEOA- 0AAK;:8 ------------------------------------------------------------------------ [2018-10-02 06:38:09] alec@php.net Description: ------------ I'm testing PHP 7.3.0RC2 (cli) (built: Oct 1 2018 11:46:48) ( NTS ) Ondrej's PPA on Ubuntu 18.04. It looks like conversion to/from UTF7-IMAP encoding is broken. See simple test script. It works as expected on PHP <= 7.2. Test script: --------------- $str = '&BCAEMARBBEEESwQ7BDoEOA-'; echo mb_convert_encoding($str, 'UTF-8', 'UTF7-IMAP') . "\n"; $str = 'Рассылки'; echo mb_convert_encoding($str, 'UTF7-IMAP', 'UTF-8') . "\n"; Expected result: ---------------- Рассылки &BCAEMARBBEEESwQ7BDoEOA- Actual result: -------------- BCAEMARBBEEESwQ7BDoEOA- 0AAK;:8 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76958&edit=1
