 ### Character set and collation naming
 
-A character set can have multiple collations, named in the `<character_set>_<collation_properties>` format. For example, the `utf8mb4` character set has a collation called `utf8mb4_bin`, which is a binary collation for `utf8mb4`. Multiple collation properties can be included in the name, separated by underscores (`_`).

 * `IS_DEFAULT`: Whether this collation is the default collation of the character set it belongs to.
 * `IS_COMPILED`: Whether the character set is compiled into the server.
 * `SORTLEN`: The minimum length of memory allocated when the collation sorts characters.
+* `PAD_ATTRIBUTE`: Whether trailing spaces are ignored during string comparison. `PAD SPACE` means that trailing spaces are ignored (for example, `'abc'` equals `'abc   '`), while `NO PAD` means that trailing spaces are significant (for example, `'abc'` does not equal `'abc   '`).
