Falling back again on the "Papal cryptography" book where Dr. Aloys Meister
writes that often severely reduced alphabets were used, sometimes only with
17 or 16 characters (h=a, q and g = c). So "lossy" coding was known and
used!

Then there is a variation on this theme:

a  d  e  i  o  l  n  s  t  u
05 10 50 51 95 01 00 19 09 55
15       90 11 59

The other letters of the alphabet were left unencoded.

Nulls:
91 a e n l t u x y

A piece of coded text would look like:

91ut0105b110015f05m15x5009f51105

I guess tricks like that would mess up the statistics of a text pretty bad.
I'm not clever enough to put it into practice immediately, but at least
these are specualtions based on historic fact.
