The Wikipedia page for WIPP still mentions that "[warning information] will be recorded in the six official languages of the United Nations (English, Spanish, Russian, French, Chinese, Arabic) as well as the Native American Navajo language native to the region, with additional space for translation into future languages. Pictograms are also being considered, such as stick figure images and the iconic The Scream from Edvard Munch's painting."
