quote('abc def') -> 'abc%20def'

    Each part of a URL, e.g. the path info, the query, etc., has a
    different set of reserved characters that must be quoted. The
    quote function offers a cautious (not minimal) way to quote a
    string for most of these parts.

    RFC 3986 Uniform Resource Identifier (URI): Generic Syntax lists
    the following (un)reserved characters.

    unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
    reserved      = gen-delims / sub-delims
    gen-delims    = ":" / "/" / "?" / "#" / "[" / "]" / "@"
    sub-delims    = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

    Each of the reserved characters is reserved in some component of a URL,
    but not necessarily in all of them.

    The quote function %-escapes all characters that are neither in the
    unreserved chars ("always safe") nor the additional chars set via the
    safe arg.

    The default for the safe arg is '/'. The character is reserved, but in
    typical usage the quote function is being called on a path where the
    existing slash characters are to be preserved.

    Python 3.7 updates from using RFC 2396 to RFC 3986 to quote URL strings.
    Now, "~" is included in the set of unreserved characters.

    string and safe may be either str or bytes objects. encoding and errors
    must not be specified if string is a bytes object.

    The optional encoding and errors parameters specify how to deal with
    non-ASCII characters, as accepted by the str.encode method.
    By default, encoding='utf-8' (characters are encoded with UTF-8), and
    errors='strict' (unsupported characters raise a UnicodeEncodeError).
