OK-ish -- thanks. * ENT_SUBSTITUTE is only available from PHP 5.4 - my production machine is PHP 5.3.3 (CentOS) * It also munges & < > -- but I can undo that with htmlspecialchars_decode() * I need to replace the Unicode Replacement Character ("\xEF\xBF\xBD") with a '?' (easy) * If I give it an over long character encoding (I tested "\xC0\xBC") it replaces each byte with a '?' - so I get two of them. It would be nice to get mb_substitute_character() working. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
