I think avoiding words that could look similar when written down would
be a good idea aswell. I searched for words that only differ by the
letters c & e, g & y, u & v and found the following:

car ear
cat eat
gear year
value valve

Other combinations could potentially be problematic depending on the
handwriting style: ft, ao, ij, vy, possibly even lt and il?
