RFC3986 defines two sets of characters you can use in a URI:

• Reserved Characters: :/?#[]@!$&'()*+,;=

  reserved = gen-delims / sub-delims

  gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@"

  sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="

  The purpose of reserved characters is to provide a set of delimiting characters that are distinguishable from other data within a URI. URIs that differ in the replacement of a reserved character with its corresponding percent-encoded octet are not equivalent.

• Unreserved Characters: A-Za-z0-9-_.~

  unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

  Characters that are allowed in a URI but do not have a reserved purpose are called unreserved.
