# 5.1. Parameter Encoding
#
# All parameter names and values are escaped using the [RFC3986] percent-encoding (%xx) mechanism.
# Characters not in the unreserved character set ([RFC3986] section 2.3) MUST be encoded. Characters
# in the unreserved character set MUST NOT be encoded. Hexadecimal characters in encodings MUST be
# upper case. Text names and values MUST be encoded as UTF-8 octets before percent-encoding them per [RFC3629].
#
# unreserved = ALPHA, DIGIT, '-', '.', '_', '~'
