Bug #72752 [Opn->Ver]: mb_convert_encoding fails to convert chars from HTML-ENTITIES to some encodings

Edit report at https://bugs.php.net/bug.php?id=72752&edit=1 ID: 72752 Updated by: cmb@php.net Reported by: contact at amb dot tf Summary: mb_convert_encoding fails to convert chars from HTML-ENTITIES to some encodings -Status: Open +Status: Verified Type: Bug Package: mbstring related Operating System: Arch Linux PHP Version: 7.0.9 Block user comment: N Private report: N New Comment: Confirmed: <https://3v4l.org/8u1h4>. The culprit is in mbfl_convert_filter_get_vtbl()[1], where the failing encodings simply assume the input is 8bit encoded. Just removing these shortcuts(?) would make the supplied test script pass (except for BASE64 encoding, which would report a).
