This is simply not the place to use a dictionary.
You don't need fast lookup from names to codes,
but something that supports incremental search.
This would enable PythonWin to sho a pop-up list after
you typed the first letters.
I'm working on a common substring analysis that makes
each entry into 3 to 5 small integers.
You then encode these in an order-preserving way. That means,
the resulting code table is still lexically ordered, and
access to the sentences is done via bisection.
Takes me some more time to get that, but it will not
be larger than 60k, or I drop it.
Also note that all the names use uppercase letters and space
only. An opportunity to use simple context encoding and
use just 4 bits most of the time.

Is there any reason why you didn't use the UnicodeData.txt file,
I mean do I cover everything if I continue to use that?
