Review Comment:
Thanks for the followup! After considering both you and @siddharthteotia 's
comments, I propose the following approach. Please let me know what you think.
TO_BASE64: byte[] -> base64 encoding ----> String
FROM_BASE64: String ---> base64 decoding -> byte[]
If user wants to encode a string using base 64, they can do
to_base64(to_utf8("hello!"))
If user wants to decode a string using base 64, they can do
from_utf8(from_base64("schcdeicei"))
They can also use other String encode/decode scheme, and Pinot currently
supports ASCII and UTF8.
