In practice, abbreviation in manuscripts often destroys information though (the same symbol replacing various strings).
Well yes, if you remove or reduce information, that will again reduce entropy. If con is replaced by 9 and cum is replaced by 9, you no longer see which one of the two it was originally, after this replacement. Information is lost.
When someone applies a homophonic cipher, such as the typical diplomatic ciphers of the renaissance (and let's ignore the role of nulls, doubles and nomenclator words) the text length is not changed, but a lot of information is added. Even though it is meaningless information, the entropy will increase.
