func:uriDecode

uriDecode(val, checked: true)

Parse an ASCII percent encoded string into a Uri according to RFC 3986. All %HH escape sequences are translated into octects, and then the octect sequence is UTF-8 decoded into a Str. The + character in the query section is unescaped into a space. If checked if true then throw ParseErr if the string is a malformed URI or if not encoded correctly, otherwise return null. Use parseUri() to parse from standard form. See Uri for a detailed discussion on standard and encoded forms.

Examples:

"foo bar".parseUri     >>  `foo bar`
"foo%20bar".uriDecode  >>  `foo bar`
