-- This pair of encoding functions is used where variable text must go in
-- button names, where the text might contain formspec metacharacters.
-- We can escape button names for the formspec, to avoid screwing up
-- form structure overall, but they then don't get de-escaped, and so
-- the input we get back from the button contains the formspec escaping.
-- This is a game engine bug, and in the anticipation that it might be
-- fixed some day we don't want to rely on it. So for safety we apply
-- an encoding that avoids all formspec metacharacters.
