+ 11. Messy code appears when reading and writing emoji emoji in mysql odbc
table
+
+ The default encoding used by Doris when connecting to odbc tables is utf8,
since the default utf8 encoding in mysql is utf8mb3, it can't represent the
emoji expressions which need 4-byte encoding. Here need to set
`charset`=`utf8mb4` when you create odbc mysql tables, then can read and write
emoji emojis normally 😀.
