Tasword didn't do sub-pixel tricks, did it? Certainly didn't on the Spectrum to get 64 columns on a 32 column display - they just drew the letters themselves instead of using system output. I'd imagine the C64 version was exactly the same?

No, in the age of CRT monitors it did not make sense to mess with subpixels as those do not have a fixed relationship between actual display RGB-triplets and the displayed bitmap. Apart from that the C64 could only display 16 colours which is not enough to play those tricks.
