PHP generated XML shows invalid Char value 27 message
A useful function to get rid of that error is suggested on this website. http://www.phpwact.org/php/i18n/charsets#common_problem_areas_with_utf-8
When you put utf-8 encoded strings in a XML document you should remember that not all utf-8 valid chars are accepted in a XML document http://www.w3.org/TR/REC-xml/#charsets
So you should strip away the unwanted chars, else you’ll have an XML fatal parsing error such as above
function utf8_for_xml($string){ return preg_replace ('/[^\x{0009}\x{000a}\x{000d}\x{0020}-\x{D7FF}\x{E000}-\x{FFFD}]+/u', ' ', $string);}Hope that saves someone else some time..
Prashant is absolutely right. You can also strip away invalid characters in Javascript by doing:
function utf8_for_xml(inputStr) { return inputStr.replace(/[^\x09\x0A\x0D\x20-\xFF\x85\xA0-\uD7FF\uE000-\uFDCF\uFDE0-\uFFFD]/gm, '');}
