What is the multiline behaviour with this crate?

[roele]

According to some dotenvy documentation for Swift, control characters are not interpreted with weak quotes. It seems this crate does not adhere to this rule, i assume multiline is implemented differently?

The use-case is following

# expected: linebreak is unprocessed
TEST_SINGLE_WEAK='{"bla":"one\ntwo"}'
# expected: line break interpreted
TEST_SINGLE_HARD="{\"bla\":\"one\ntwo\"}"
# expected: line break interpreted
TEST_MULTILINE="one
two"
