| + Whether the text encoding auto detection logic was attempted for a web page. |
| + The logic is triggered when the parser fails to find the encoding method |
| + from other signals such as http header, meta tag, BOM, etc. |
| + |
| + If the logic successfully detects a new encoding method which is different |
| + from the default one, the result is reported through |
| + AutodetectEncoding.Detected with the encoding method (see below). Otherwise |
| + - i.e. detection logic somehow fails to work for the page or the detected |
| + one is same as the default - no result is reported. |
