I use the term "function" not applied to the era and mathematical developments of the era, but as the general notion.
Basically, function is a rule that associates or "maps" inputs (arguments) to outputs (values). If you have no arguments, you have no function values. Likewise, if the presence of a "covering" gallows character indicates that some rule should be applied to the subsequent characters being "covered" (e.g. Voynichese "pABC" means plain text "XYZ"), then there is no answer what does a gallows character mean or indicate when it does not cover anything.
