What about decoding ?

[mithuns]

I am a bit new to this , so forgive me if I sound like I dont understand this, I think the encoding is non-deterministic, for instance, there are multiple encodings that can be produced from a source String, does that make decoding impossible ? Is there a decoder available somewhere ?

It's very deterministic, but decoding is annoying because it generally requires an actual browser and a js runtime for it to run properly. A decoder could certainly be written, but it would have to emulate the runtime environment pretty well, or make some possibly very brittle assumptions and apply the same logic a js runtime would to the characters (stuff like what does it mean to add a number to a char vs a char to a number as js does not treat these the same).

@kernelsmith's is right. Prepack was as he described. I haven't tried it on hieroglified code, but it may work.

这是非常确定的，但解码很烦人，因为它通常需要一个实际的浏览器和一个js运行时才能正常运行。解码器肯定可以编写，但它必须很好地模拟运行时环境，或者做一些可能非常脆弱的假设，并将js运行时应用于字符的相同逻辑（类似于添加数字的意义）一个char与一个char到一个数字，因为js不会对它们进行相同的处理）。

我对此有点新意，所以请原谅我，如果我听起来像我不明白这一点，我认为编码是非确定性的，例如，有多种编码可以从源字符串产生，这会使解码变得不可能？ 某处有解码器吗？

我还 写了一个解码程序看我的github上有。 I also wrote a decoding program to see on my github. https://github.com/masx200/JSfuck-and-hieroglyphy-Decoder-and-ENCODER
