protected property UrlGenerator::$decodedChars

This array defines the characters (besides alphanumeric ones) that will not be percent-encoded in the path segment of the generated URL.

PHP's rawurlencode() encodes all chars except "a-zA-Z0-9-._~" according to RFC 3986. But we want to allow some chars to be used in their literal form (reasons below). Other chars inside the path must of course be encoded, e.g. "?" and "#" (would be interpreted wrongly as query and fragment identifier), "'" and """ (are used as delimiters in HTML).

  // the slash can be used to designate a hierarchical structure and we want allow using it with this meaning
  // some webservers don't allow the slash in encoded form in the path for security reasons anyway

  '%2F' => '/',
  // the following chars are general delimiters in the URI specification but have only special meaning in the authority component
  // so they can safely be used in the path in unencoded form
  '%40' => '@',
  '%3A' => ':',
  // these chars are only sub-delimiters that have no predefined meaning and can therefore be used literally
  // so URI producing applications can use these chars to delimit subcomponents in a path segment without being encoded for better readability
