PCDATA invalid Char value 31

[math62400]

First of all, thanks !!
Your tools helps me a lot for UTF8 string conversion

I would save a string in XML and I would like to format it in UTF8,
But I have this error when I try to load XML after save.

DOMDocument::load(): PCDATA invalid Char value 31

I look for an answer in Google and I found that.

http://stackoverflow.com/questions/14463573/php-simplexml-load-file-invalid-character-error

function utf8_for_xml($string)
{
    return preg_replace ('/[^\x{0009}\x{000a}\x{000d}\x{0020}-\x{D7FF}\x{E000}-\x{FFFD}]+/u', ' ', $string);
}

Can you tell me if there is an other way to solve it?

Hey, you probably already solve it, but this is nothing to do with utf8 (specifically):

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
