I wrote the below code

    def unquote_quote(segment):
        segment = unquote(segment)
        segment = quote(segment, safe=((RFC3986_SUBDELIMS + RFC3986_GENDELIMS) + '~'))
        return force_text(segment)
    try:
        (scheme, netloc, path, query, fragment) = urlsplit(url)
    except ValueError:
        return unquote_quote(url)
    try:
        netloc = netloc.encode('idna').decode('ascii')
    except UnicodeError:
        return unquote_quote(url)
    if query:
        query_parts = [(unquote(q[0]), unquote(q[1])) for q in parse_qsl(query, keep_blank_values=True)]
        query = urlencode(query_parts)
    path = unquote_quote(path)
    fragment = unquote_quote(fragment)
    return urlunsplit((scheme, netloc, path, query, fragment))
