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.
