Title: Strings::normalize should remove C1 control codes as well

Strings::normalize should remove C1 control codes (U+0080 to U+009F) as well. This would however be a BC break because currently Strings::normalize works for non-utf8 strings as well.

This would also make Strings::normalize behavior closer to what Http\RequestFactory::NONCHARS is used for.
