Neo,
It appears to me the left vertical leg of the letter "r" in "brown" is the same as the left vertical leg of the letter "n". The curved part of the "r" looks like the curved part of the "n". Further, the circular part of the "b" looks suspiciously similar to the rightmost 135 degrees of the "o". Cannot, then, this example be further "normalized"?
