 +====== Character Sets ======
 +  * List available character sets
 +    * SHOW CHARACTER SET;
 +  * List collation for character set
 +    * SHOW COLLATION LIKE 'latin1%';
 +  * Find character set and collation for a specific database
 +    * SHOW CREATE DATABASE databasename;
 +  * Find character set and collation for a specific table
 +    * SHOW CREATE TABLE tablename;
 +  * Find character set and collation for columns
 +    * SHOW FULL COLUMNS FROM tablename;
  
 +===== Changing/Setting the Character Set =====
 +Initially, the server character set and collation depend on the options that you use when you start mysqld. You can use --character-set-server for the character set. Along with it, you can add --collation-server for the collation. If you don't specify a character set, that is the same as saying --character-set-server=latin1. If you specify only a character set (for example, latin1) but not a collation, that is the same as saying --character-set-server=latin1  --collation-server=latin1_swedish_ci because latin1_swedish_ci is the default collation for latin1. 
 +
 +===== Notes =====
 +  * Two different character sets cannot have the same collation.
 +  * Each character set has one collation that is the default collation. For example, the default collation for latin1 is latin1_swedish_ci. The output for SHOW CHARACTER SET indicates which collation is the default for each displayed character set.
 +  * There is a convention for collation names: They start with the name of the character set with which they are associated, they usually include a language name, and they end with _ci (case insensitive), _cs (case sensitive), or _bin (binary).
