Rather than "bug", we are talking about invalid XML. It'd be interesting
to inspect the XML source code and the exact error message.

The problem is that computers can only handle binary numbers (but not
letters) and there isn't a universal mapping between letters and
numbers. Instead, you have a few hundred mappings called character sets
(or charsets).
Most likely, you want to generate an XML document that uses the UTF-8
charset. That's a nice option: it's widely supported and it can
represent almost any character that exists. However, there's an
important pre-requisite when you work with charsets: you must find out
what charset your app is using so you can decide whether you need to
perform any sort of conversion. Can you obtain that information?

Are you sure you need HTML entities in the first place?
