Ok... sorry for giving you incorrect information. I looked at
phpMyAdmin's code and saw how it is handled. As far I I understand
code in PMA_DBI_postConnect(), your data is guaranteed to come in
UTF-8 encoding. So you don't have to worry about anything, XMLWriter
is safe to use.
As for connection parameters, you can look ar MySQL's documentation
[1] in your free time, as there is no need to change anything. Sorry
for confusing you.
