See the explanation below. There is a general problem with IRI conversion with some protocols that are in violation of the URI specification. Consider the following two IRIs:: magnet:?xt=uri:whatever itms-services://?action=download-manifest After parsing, we don't know if the scheme requires the ``//``, which is dropped if empty, but conveys different meanings in the final URL if it's present or not. In this case, you can use ``safe_conversion``, which will return the URL unchanged if it only contains ASCII characters and no whitespace. This can result in a URI with unquoted characters if it was not already quoted correctly, but preserves the URL's semantics. Werkzeug uses this for the ``Location`` header for redirects. .. versionchanged:: 0.15 All reserved characters remain unquoted.
