> User cannot specify utf8 strings in the query, both for selection and filtering. Mysql syntax should be followed: 
> select _utf8 'string' from <TableName>
> select <selectExpr> from <TableName> where col = _utf8 0x<HexValue>
> To start with, utf8 strings should be supported. Support for other character sets can be added in the future on demand.
> The identifiers (table name/column name etc.) cannot be utf8 strings, it is only for the data values.
> Although, in create table, the user has the option of specifying sorted columns, he does not have the option of specifying whether they are ascending or descending.
> Create Table syntax should be enhanced to support that.
