Reserved characters

Reserved characters should not be encoded when they appear in their conventional meaning in a URL. For example, do not encode the slash (⁜/⁜) when using it as part of the URL syntax. Only encode unsafe characters (defined below) in your URLs.

The following table lists reserved characters.

	Characters	Hex	Dec
$	Dollar	24	36
&	Ampersand	26	38
+	Plus	2B	43

?	Question mark	3F	63
