To make sure XML is UTF-8

[Tiong Jeffrey]

Hi,

Thought this is not directly related to Solr, but I have a XML output from
mysql database, but during indexing the XML output is not working. And the
problem is part of the XML output is not in UTF-8 encoding, how can I
convert it to UTF-8 and how do I know what kind of coding it uses in the
first place (the data I export from the mysql database). Thanks!
