The Imperial Orthographic Congress
Basically, every twenty years the Empire issues new standards of spelling for all Official Imperial documents and schools. This keeps the spelling of
Gallan,
Sylean, and other languages vital to the Third Imperium both standardized and phonetic.
They also work to keep the typefaces of the 3I standardized and readable.
As agents studying the languages of the 3I can show up anywhere, it's a solid cover for other sorts of agents.
