Agreed; the naive implementation would need to less naive and pay closer attention to the ABNF for `ucschar` and `ipchar` in the spec. Along those lines, I think there might need to be two additional changes/additions to help with encoding for RFC 3987 and WHATWG-URL component values: - `http_build_query()` would need PHP_QUERY_3987 and PHP_QUERY_WHATWG flags and corresponding logic (or entirely new functions); and - `parse_str()` would need a corresponding `mb_parse_str()`. -- pmj
