Translating escape sequence

[J. Landman Gay]

Thanks. I actually was using jsonImport() with these strings 
successfully (no wrapper required) but it has a bug on Android that 
makes it unuseable. That's what caused the problem in the first place, 
because jsonToArray() doesn't deal with escape sequences.

So I went ahead and wrote a decoder for escaped sequences that works, 
but found out I still can't use it. If I replace the escapes before 
using jsonToArray(), jsonToArray throws an error; it can't deal with the 
UTF16 strings. And I can't run my decoder through the keys of the 
converted array after jsonToArray is finished, because they are already 
munged into garbage characters by then.

So I'm stuck, I don't see any way to deal with these. I'll put in a bug 
report about jsonImport() but it will probably be a while before it gets 
fixed.

I hope someone else has an idea.
