- * On top of that the RFC3986 (https://tools.ietf.org/html/rfc3986#section-2.2) defines some extra characters to be encoded. Most browsers do not encode them in encodeURI https://github.com/whatwg/url/issues/369 so it may be safer to also encode !'()*. Leaving unencoded only ASCII alphanum plus -._~
- * This extra safety should be applied to query by patching the string returned by encodeURIComponent
- * encodeURI also encodes [\]^
- * \ should be encoded to avoid ambiguity. Browsers (IE, FF, C) transform a \ into a / if directly typed in
- * ` should also be encoded everywhere because some browsers like FF encode it when directly written while others don't
