I must confess that I have an irrational fondness for the use of weird symbols in math and technical documents, whether it's for a homework assignment in school or a white-paper for work.
My unit tests are literally full of hieroglyphics. My favorite design doc to this day is one where I sprinkled Sumerian cuneiform throughout the text, e.g. 𒀭𒄑𒉋𒂵𒎌 and 𒂗𒆠𒄭 (Gilgamesh and Enkidu) instead of Alice and Bob.
