Should it be \\/ instead? Do you have an example where you use it?

[YK-Samgo]

As shown in #293 , json use \/ in unix path string like {"path":"\/var"}.

pyhocon does not parse it correctly as jq does.

# echo '{"path":"\/var"}' | jq .
{
  "path": "/var"
}
# echo '{"path":"\/var"}' | pyhocon
{
  "path": "\\/var"
}

Python handles \ in a strange way. '\/', '\\/', "\/" and "\\/" all work.
