>>12540010>isn't stroke count obvious?Not always. Some radicals can look like they might have more strokes than they actually do, like 弓 (which looks it it could have 7 strokes, but has only 3) and ム (which looks like it might have 3 strokes but has only 2 instead).
Google Translate's kanji detection tool relies on the assumption that the number of strokes is more or less ok, so if you cut out or add a few strokes, the right character might not pop up as a suggestion.
