jsc decoding spy

First use 

JS_DecodeScript decompile bytecode bytes get jsc

 

reuse

size_t nchars;

if (!JS_DecodeBytes(cx, bytes, nbytes, nullptr, &nchars))

return nullptr;

jschar *chars = static_cast<jschar *>(JS_malloc(cx, nchars * sizeof(jschar)));

if (!chars)

return nullptr;

JS_ALWAYS_TRUE(JS_DecodeBytes(cx, bytes, nbytes, chars, &nchars));

 

Out of chars transcoding translated into utf-8 string is stored in the file

Finally free (chars); release the memory
