Uri.unescapeString
string unescapeString(string escapedString, string illegalCharacters = null)Unescapes a whole escaped string.
If any of the characters in illegal_characters or the NUL character appears as an escaped character in escaped_string, then that is an error and null will be returned. This is useful if you want to avoid for instance having a slash being expanded in an escaped path element, which might confuse pathname handling.
Parameters
escapedString | an escaped string to be unescaped. |
illegalCharacters | a string of illegal characters not to be allowed, or null. |
Returns
an unescaped version of escaped_string.
