JSON parsing: fix incorrect sign-extension for decoding bad escapes
The parser was lenient in accepting backslashes followed by invalid
characters, but accidentally sign-extended everything above 0x7f causing
broken outputs that weren't valid UTF-16 either.
For example, the sequence "\\\xff" (backslash followed by 0xff) produced
sequence "\ud7bf\udfff" (U+D7BF is not a surogate pair).
