As seen in the output Go indeed considers string literal as utf-8 encoded stream of chars but trying to index a string will not give you expected behaviour in this case I needed ವ at 0 but got \xe0 which is first byte of utf-8 encoded \u0cb5 which is \xe0 \xb2 \xb5.

Language does allow us directly write any language as string in Go but it doesn't understand Unicode code points natively, but strings library does interpret the unicode properly as well as range key word on string.
