XML Parsing Error: not well-formed

Question

I am creating a sitemap XML from my database it's about videos sitemap. In XML, I am fetching the video title as title and description as description, but there are some titles and descriptions written in Thai, Portuguese, German, and other languages. While generating the XML through PHP I am facing a problem that says:

"XML Parsing Error: not well-formed".

Generation of the XML stops after encountering this error.

XML Parsing Error: not well-formed
Location: http://localhost/mydesk/sitemap.php
Line Number 24489, Column 69:

I observed it contained invalid characters like listed below, and I have replaced all types of these characters, but I realized there are other characters being used in other languages.

Is there any way to handle this issue that supports all languages?
