In section 2.3.2 (Parsing URLs):

# Add all characters with codepoints less than or equal to U+0020 or
# greater than or equal to U+007F to the <unreserved> production.

And RFC 3986 says:

# Characters that are allowed in a URI but do not have a reserved
# purpose are called unreserved.  These include uppercase and lowercase
# letters, decimal digits, hyphen, period, underscore, and tilde.
#
#     unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"
