> The current code generation do not support Unicode, "\u0001" will be generated to "\\u0001",
function call like concat(str, "\u0001") will lead to wrong result.
> This issue intend to handle char/varchar literal correctly, some examples followed as
below.
> literal: '\u0001abc'    ->   codegen:  "\u0001abc"
> literal: '\u0022\'         ->   codegen:  "\"\\"
