> My question is more fundamental, why are SQL strings escaped in the first
place? Should it not be up to the frontend language to escape such strings?
I.e. scala/java/python should handle replacing things such as \n with the
newline or replacing unicode sequences with their corresponding symbols.
Based on my understanding, the escape behavior/definition in SQL is
different from the frontend language. That is why we need to call
`unescapeSQLString` on the string literals. Let us discuss f2f how to handle
the case tomorrow.
