+    * CID's strings are UTF8. If character_set_client is not UTF8 but latin1 for example (unfortunatly that's the common case), non-latin1
+    * characters will appear garbled when manually browsing the db, but they should show OK in CID's web pages.
+    *
+    * When authenticating below, we use MySQL's MD5 function. From my tests, it looks like the argument of this function
+    * gets automatically converted to the charset of that field. Sorta like if we had implicitly MD5(CONVERT(arg using charset)).
+    * When the tables are build during setup, the charset of string fields are set accordingly to the my.cnf directives
+    * character-set-server and collation-server.
+    * If those directives don't match character_set_client, the conversion inside MD5 will in fact transform the string, and we'll
+    * get the MD5 of a different string than what we had intended (well, only if the string contains non-latin1 characters).
+    * For this reason we have to override that conversion, converting to the charset specified in character_set_client, as shown below.
