* More formatting changes

* Fix an unintended switch/case fallthrough (the error got caught soon afterwards, so this never really caused problems)
* Fix a typo in the mysql fallback charset mappings (119 should’ve been 199)
* Fix a charset confusion issue (SPMySQL’s compiled-in C strings are in UTF-8, not the connection encoding of the mysql connection)
