When visiting a URL with a hash (something formatted akin to https://gridsome.org/docs/dynamic-routing/#file-based-dynamic-routes), the hash gets stripped out when the path is updated to include the /en prefix. This simply passes the hash on (if it exists), allowing the browser to still navigate to the correct spot on the page after the redirect has taken place.
