> The current lpad and rpad don't support the multibyte character at "str" and "pad".
> For example, we can see the following result.
> {code}
> hive> select name from sample1;
> OK
> tokyo
> ＴＯＫＹＯ
> hive> select lpad(name, 20, '*') from sample1;
> OK
> ***************tokyo
> *****ＴＯＫＹＯ
> {code}
> This is improved as follows.
> {code}
> hive> select lpad(name, 20, '*') from sample1;
> ***************tokyo
> ***************ＴＯＫＹＯ
> {code}
