I would personally prefer if the string serialization were able to (de)serialize
NULL strings since NULL strings are valid GValues. This is because at some point
someone might get the idea to serialize GObject properties with this API and
there it is definitely allowed.

FWIW, the D-Bus glib bindings have the same issue. Last I looked they just
errored out on NULL strings which wasn't helpful at all for me.

Next question: Do we serialize to UTF-8 or ASCII? In any case: How should we
handle control characters like line feeds, backspace and so on?


My solution would be to invent some sort of escape character (possibly % to
mimic printf) and use that to escape special cases. % => %%, <someweirdchar> =>
%<unicode-hexvalue-of-weird-char> and NULL => %
