The code in the source library, file 'xml_element.c' seems to have a bug in function create_xml_escape. The same bug would apply for characters 100 to 109, however that does not happen because those characters are not encoded as entities in the first place. Test script: --------------- echo xmlrpc_encode(chr(199).chr(200).chr(209).chr(210); Expected result: ---------------- <?xml version="1.0" encoding="utf-8"?><params><param><value><string>&#199;&#200;&#209;&#210;</string></value></param></params> Actual result: -------------- <?xml version="1.0" encoding="utf-8"?><params><param><value><string>&#199;&#20;&#29;&#210;</string></value></param></params> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80559&edit=1
