attribute escape_js_separators_in_json

If true, encode LINE SEPARATOR (U+2028) and PARAGRAPH SEPARATOR (U+2029) as escaped unicode sequences (‘\u2028’ and ‘\u2029’). Historically these characters were not valid inside JavaScript strings but that changed in ECMAScript 2019. As such it’s no longer a concern in modern browsers: caniuse.com/mdn-javascript_builtins_json_json_superset.
