Hi Patrick,

This was added to libyaml a couple months ago:

https://github.com/yaml/libyaml/commit/66bcb985569e7b643823c9ba1aeb47892583aeef

Note that it's on the yaml-1.2 branch. Also note that this new github repo is the canonical source at this time.

Cheers, Ingy

I attempted to submit a feature request ticket for libyaml:

http://pyyaml.org/newticket?component=libyaml

but it rejected my ticket, telling me it was spam.  (I could go off on a
whole rant about how so-called "spam filtering" makes it impossible for
legitimate users to get anything done these days, but that would be
off-topic.)

Anyway, since I can't submit a ticket, sending the feature request to
this list seemed like the next-best thing.

Here is the text of the ticket I attempted to submit to libyaml:

YAML 1.2 adds support for the escape sequence "\/", which was not
present in YAML 1.1:

http://www.yaml.org/spec/1.2/spec.html#id2776092

YAML 1.2 added this escape sequence in order to be compatible with JSON.
  (Since YAML's goal is to be a superset of JSON.)

Although libyaml is only a YAML 1.1 parser, it would be nice to have
this feature, and adding it shouldn't cause any trouble with parsing
YAML 1.1.

This is all that's needed:
