SPGetQueryString no longer plays nice with query string parameters that were encoded with ddwrt:UrlEncode. ddwrt:UrlEncode uses a '+' to encode spaces.
Both used to return 'Jim Bob' with SPGetQueryString. SPGetQueryString now returns "Jim Bob" and "Jim+Bob". I'm thinking of forking the 2014 version and changing SPGetQueryString back to to the older version. Was it changed to fix a bug that
will be reintroduced if I go back to the old way?
