> Support the CONVERT function, to convert strings from one character set to another.
> CONVERT is defined in SQL:2011 as a feature called {{<character transliteration>}}. Here is an example:
> {code}
> SELECT * FROM emp WHERE CONVERT(name USING UTF16) = u&'\82f1\56fd'
> {code}
> The [MySQL site|https://dev.mysql.com/doc/refman/8.0/en/cast-functions.html#function_convert] has other examples.
