While I was bored on a camping trip with no web and just a phone with character picker, I found two characters that I realized said “they/them”. Here they are: ᵺ㏟
The characters in UTF16LE text encoding under N64 executable wordswapping result in the hexadecimal data of $df337A1D, which can be read as “defeat AIDS”, which is quite a happy accident. All because I was bored with no internet access and limited battery. I do other stuff while bored that ends up being quite deep later on in ways far beyond what I thought then.
The characters in Unicode are officially the International Phonetic Alphabet symbol “theta” (for the first character, which maps to the real “th” sound in the alphabet), and the second character is “A over M”, which is used for the physics expression of the same name which is used for acceleration and mass among other things. In physics (class), a question reading “What is the theta of a over m?” is theoretically a way to slyly express your pronouns and also convey a hidden message about defeating AIDS too with just one rhetorical question about physics.

Enjoy this intriguing thing!
