evnp	ba59201217	Don't escape HTML chars when converting to json json.Encoder and json.Marshal implicitly use HTMLEscape to convert >, <, &, with \u003c, \u003e, \u0026. This behavior carries over to yq, where chars will be escaped when outputting json but not when outputting yaml. This changeset disables this behavior via encoder.SetEscapeHTML(false). Unfortunately there is no equivalent option for json.Marshal, so its single usage has been replaced with an encoder (with escaping disabled).	2021-01-18 13:33:02 +11:00
