Issue Description:

Assume I want to define a hardcoded JSON object:

let json = """
{
  "text": "This is text with \"quotes\" in it..."
}
"""

both the regular `"` as the `"` are interpreted the same.
json will be:

"{\n  \"text\": \"This is text with \"quotes\" in it...\"\n}"

which will invalidate my json object.

The expected interpretation would be:

"{\n \"text\": \"This is text with \\\"quotes\\\" in it...\"\n}"

Comment by Kyle Macomber (JIRA)

This appears to behave to spec. From the SE-0168 decision rationale:

It should be clarified that multiline strings support the same escapes and interpolations as single-line strings. This allows a literal """ to be written """.

Note that you can use SE-0200 Raw Strings to instead of all the backslashes:

let json = #"""
{
  "text": "This is text with \"quotes\" in it..."
}
"""#

Or:

let json = #"{ "text": "This is text with \"quotes\" in it..." }"#
