		176	If C<$enable> is true (or missing), then the C<encode> method will encode
		177	the resulting JSON text as latin1 (or iso-8859-1), escaping any characters
		178	outside the code range C<0..255>. The resulting string can be treated as a

		185
		186	The main use for this flag is efficiently encoding binary data as JSON
		187	text, as most octets will not be escaped, resulting in a smaller encoded
		188	size. The disadvantage is that the resulting JSON text is encoded
		189	in latin1 (and must correctly be treated as such when storing and
		190	transfering), a rare encoding for JSON. It is therefore most useful when

		617	no way to configure JSON::XS to output a data structure as valid YAML.

		623	my $yaml = $to_yaml->encode ($ref) . "\n";
		624
		625	This will usually generate JSON texts that also parse as valid
		626	YAML. Please note that YAML has hardcoded limits on object key lengths
		627	that JSON doesn't have, so you should make sure that your hash keys are
		628	noticably shorter than 1024 characters.
		629
		630	There might be other incompatibilities that I am not aware of. In general

		698
		699	First of all, your JSON decoder should be secure, that is, should not have
		700	any buffer overflows. Obviously, this module should ensure that and I am
		701	trying hard on making that true, but you never know.
		702
		703	Second, you need to avoid resource-starving attacks. That means you should
		704	limit the size of JSON texts you accept, or make sure then when your
		705	resources run out, thats just fine (e.g. by using a separate process that
		706	can crash safely). The size of a JSON text in octets or characters is
		707	usually a good indication of the size of the resources required to decode
		708	it into a Perl structure.
		709
		710	Third, JSON::XS recurses using the C stack when decoding objects and
		711	arrays. The C stack is a limited resource: for instance, on my amd64
		712	machine with 8MB of stack size I can decode around 180k nested arrays but
		713	only 14k nested JSON objects (due to perl itself recursing deeply on croak
		714	to free the temporary). If that is exceeded, the program crashes. to be
		715	conservative, the default nesting limit is set to 512. If your process
		716	has a smaller stack, you should adjust this setting accordingly with the
		717	C<max_depth> method.
		718
		719	And last but least, something else could bomb you that I forgot to think
		720	of. In that case, you get to keep the pieces. I am always open for hints,
		721	though...
