However, known cases of the diffusion of writing, such as Sequoyah's invention of the Cherokee syllabary after seeing the power of English-language newspapers, or Uyaquk's invention of the Yugtun script inspired by readings from Christian scripture, involved greater contact than the signing of a single treaty.
Kendte eksempler på diffusion af skrift, såsom Sequoyahs opfindelse af cherokeealfabetet efter at have set de engelsksprogede avisers magt, eller Uyaquks opfindelse af yugtunalfabetet inspireret af kristne tekster, involverede langt mere kontakt end blot underskrivelsen af en aftaler.
