Return a string representing 's'. Treat bytestrings using the 'encoding'
codec.
If strings_only is True, don't convert (some) non-string-like objects.

Convert an Internationalized Resource Identifier (IRI) portion to a URI
portion that is suitable for inclusion in a URL.
This is the algorithm from section 3.1 of RFC 3987, slightly simplified
since the input is assumed to be a string rather than an arbitrary byte
stream.
Take an IRI (string or UTF-8 bytes, e.g. '/I ♥ Django/' or
b'/I ⥠Django/') and return a string containing the encoded
result with ASCII chars only (e.g. '/I%20%E2%99%A5%20Django/').

Convert a Uniform Resource Identifier(URI) into an Internationalized
Resource Identifier(IRI).
This is the algorithm from section 3.2 of RFC 3987, excluding step 4.
Take an URI in ASCII bytes (e.g. '/I%20%E2%99%A5%20Django/') and return
a string containing the encoded result (e.g. '/I%20♥%20Django/').

As per section 3.2 of RFC 3987, step three of converting a URI into an IRI,
repercent-encode any octet produced that is not part of a strictly legal
UTF-8 octet sequence.

Encode certain chars that would normally be recognized as special chars
for URIs. Do not encode the ' character, as it is a valid character
within URIs. See the encodeURIComponent() JavaScript function for details.
