Six abstract characters (hard dotted, dotless, soft dotted in 2 cases)
for four coded characters, something has to break somewhere.

With the current practice, there is inherent ambiguity.

The current practice is tolerable only in the presence of locale
information. In which case the addition of combining dots in case
transformation is useless, and in fact harmful as Richard showed.

Adding more characters (as in creating the hard dotted form by using the
dotless + combining dot) breaks current practice.
