------------------------------------------------------------------

* Standard has CHARACTER_LENGTH and CHAR_LENGTH as synonyms, can you please add that as well?
* Please use GenericUDF interface instead of UDF. UDF interface is deprecated and meant to be removed.
* Please add tests for NULL values. Should return NULL for both functions.
* Also add test for vectorized octet_length

> SQL defines standard ways to get number of characters and octets. SQL reference: section 6.28. Example:
> vagrant=# select character_length('欲速则不达');
>  character_length
> ------------------
>                 5
> (1 row)
> vagrant=# select octet_length('欲速则不达');
>  octet_length
> --------------
>            15
> (1 row)
