    Hmmm ... don't know what you mean with the "Other" row exactly, but "⁒" U+2052 might be a better character for "AND Other"

      @Maex the DOT is also used to denote AND. I just happens that there are multiple DOT variants in unicode, so I gave two examples.

        I have never seen dots being used as AND. One other thing I have just noticed is that in C the logic AND and OR are written && and ||. You used the binary AND/OR operators. So int a = 2, b = 4; if (a & b) printf("true\n"); would not print "true". But int a = 2, b = 4; if (a && b) printf("true\n"); would print "true".

        Oh and bitwise XOR is ^ (caret) and (bitwise) 1-complement is ~ (tilde) in C.
