Signing Strings Encoded in Micheline Expressions

[Geo25rey]

We are trying to have users sign a string which is used to generate another asymmetric key pair. We initially thought to use the raw signing type, but that isn't well supported by most Tezos wallet providers. In order to get around this, @klassare from Kukai recommended that we use Micheline encoding for a string instead. When I tested this, the string was rendered with quotes around it and with newlines escaped. After looking into the Kukai implementation a bit, I found that they use emitMicheline() to create the rendered text. Is that its intended use? Why are strings ran through JSON.stringify() when converting a Micheline expression to a string? Is the output of emitMicheline() supposed to be ran through JSON.parse() afterwards to get the JSON equivalent to the original Micheline expression?
