Otherwise the feature will be an annoyance.

It's also dependent on which characters they are - Cyrillic, Han, Greek, Hebrew etc should be expected to appear in long runs, perhaps with runs of ASCII and/or other characters interleaved. Latin-1 on the other hand would normally appear individually or in very short runs mixed in with ASCII.

There is no single heuristic that can be used to identify "suspicious" characters.
