My thinking is that there are only two things that have the ability to
"cost" time. One is tape management, but using an object that acts like
an array which is indexed in makes this fast except when we need to
expand it, but that will generally amortize to a small value. (Letting
the string class do that isn't a bad option).
The second "costly" operation is looking up the rule based on current
state / tape symbol. For speed this really needs to be O(1) (at least
amortized). If we reduce our state and input symbols to an internal
numbering of 0-n an array works great. If we limit our states to 'ascii
characters' then the 256 x 256 array isn't outlandish in space
requirements for modern machines.
If you want full Unicode characters, then either you need the conversion
to a simple 0-n enumeration, or going to a hash table to store the
rules. The question becomes which cost more the input/output conversion
to use 0-n values, or hashing (and handling the possible collisions).
My thought is that in the 0-n enumeration, the table is "dense" in the
sense that all non-terminal state will be fully filled out. (And
terminal states don't actually need an entry, just a value recognized as
terminal).
