* FIXME Current behavior for invalid UTF-8 sequences is

* They're all marked "bug:" below, and are to be replaced by
* correct ones as the bugs get fixed.
*
* The JSON parser rejects some invalid sequences, but accepts
* others without correcting the problem.
*
* We should either reject all invalid sequences, or minimize
* overlong sequences and replace all other invalid sequences by a
* suitable replacement character. A common choice for
* replacement is U+FFFD.
*
* Problem: we can't easily deal with embedded U+0000. Parsing
* the JSON string "this \\u0000" is fun" yields "this \0 is fun",
* which gets misinterpreted as NUL-terminated "this ". We should
* consider using overlong encoding \xC0\x80 for U+0000 ("modified
* UTF-8").
*
* Most test cases are scraped from Markus Kuhn's UTF-8 decoder
* capability and stress test at
* http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-test.txt
