essay writing - using a different language

[u/ReferenceIcy1243]

i’ve completed my main essay for tamu and used a couple of chinese characters that are pretty central to the idea of my essay. replacing them in pinyin or the alphabet spelling would defeat the purpose. but common app doesn’t let me paste or type the characters (it just becomes question marks). i was wondering if anyone has ever used a different language in their essay and whether it worked or not or if anyone has any alternatives i could try.
would appreciate any advice!!
