A subtile but important point is that character set encoding has nothing to do with the actual shape of the characters being encoded.

for (int j=1; j<3; j++) { if (((col0>>i & 0b11) == (3-j)) && ((col1>>i &0b11) == j)) { col0R = col0R | 1<<((i*2)+j); col1L = col1L | 1<<((i*2)+3-j); } }
The variables col0 and col1 are two successive 8-pixel high columns in the normal-resolution character, and col0L, col0R, col1L, and col1R are the 16-pixel high left and right versions of these in the double-resolution character.
