Is there a way to serialize white space ?

[KristianIvarsson]

Consider this (roundtrip) code

   auto source = fkyaml::node::mapping();
   source.as_map()["alpha"] = " data ";
   auto target = fkyaml::node::deserialize( fkyaml::node::serialize( source));
   assert(source.as_map().at("alpha").as_str() == target.as_map().at("alpha").as_str());

The strings are not by default written with \" or \'and thus the strings are trimmed during deserialize()

Writing a newline makes the resulting string be encapsulated thogh and thus they are equal after a roundtrip

   source.as_map()["alpha"] = " data\nmore ";

I cannot see if there are any possible directives you can pass to the serialize-mechanism that you always want strings to be encapsulated with quotes or apostrophes

Does anyone know or is this just a flaw in the library?

p.s.
Of cource you can add quotes by your self, but then there will (sometimes) be double quotes (hence, the new-line-scenario)
d.s.

Right now that is not possible. I have a PR (#508) that could be extended to handle this situation. There just need to add an space into the pattern.
