1) MySQL 6 is not supported

2) Joomla! 1.5, 1.6/1.7 and 2.5 in the default installation use always utf-8 encoding and database collation. It is not recommended to change this setting to other than utf-encodings. However, it may be sometimes useful to change the database collation from "utf8_general_ci" to a more appropriate setting for your language. For example to "utf8_polish_ci" for Polish language or to "utf8_roman_ci" for German or French.
It is especially useful for languages with special non-latin letters.

3) Some providers seem to provide this functionality within the PHP configuration, but at the same time outgoing connections are blocked on the firewall.
Please ensure that this functionality is enabled and also that it is indeed possible to use it.

4) SQLite can be supported directly via the SQLite extension or through the PHP Data Objects extension.
