The creation of ASCII circa 1963 was a profound move by the US

in ‘covert’ secret communications and more precisely the denary
representation of this set that is comprised of the positive integers
32 to 126 inclusively, as the encryption data for writing ciphers.
However, ASCII has now been replaced by Unicode:

If you want your crypto system to by forward looking rather than
backward looking then you need to drop ASCII, which is now obsolete,
and move over to Unicode.

A failure to support Unicode is likely to impede use of your system at
the proposal stage. Almost all proposals will be required to support
Unicode; and any that fail to do so will not progress any further.
