Not all special characters are escaped correctly

[jorangreef]

file-url does not escape paths containing &, = and : correctly.

Can you provide an example input and output that is incorrect? Or even better a failing test?

[jorangreef]

I think this should remain open? I don't think there has been any fix or test for this?

The example input which needs to be escaped (&, = and :) has already been provided.
