Seems so, I wonder if an improvement specific to base64 translation couldn't be to force 1 char = 1 token (as computation power grows) ? or even further, 1 bit

Seems so, I wonder if an improvement specific to base64 translation couldn't be to force 1 char = 1 token (as computation power grows) ? or even further, 1 bit = 1 token, that could potentially help figuring out connections with arithmetic ?
