If Unicode defines the rule for initial&#x2F;medial vs. final ſigma, I wonder why it doeſn&#x27;t do the ſame for long vs. ſhort s.<p>More seriously, for encoding purposes shouldn&#x27;t it be up to the application using the encoding to choose the right character, not up to the encoding system to specify the algorithm? But maybe I&#x27;m missing something.
