Assigning $ref to a path that has a pound sign throws an error

[c3-antonytejakusuma]

It seems like since the # sign is a reserved character in resolving $ref, the following path cannot be used as a value to $ref: ../path/to/Some#Directory/schema.json. The following error will be shown:
Unable to load schema from '..path/to/Some': ENOENT: no such file or directory, open .

Is there a way to use a path that has a pound sign in this case? How can I escape the pound sign in the path?

You would need to percent encode the hash/pound sign, as JSON Schema references are URIs.
If some code choose to treat it as a file path, that's allowed, but not defined in the JSON Schema specification.
