I have an apostrophe and it’s super annoying as some companies see it as a SQL injection hack and sanitize it.
My surname contains a character that’s only present in the Polish alphabet. Writing my full name as is broke lots of systems, encoding, printed paperwork and even British naturalisation application on Home Office website. My surname was part of my username back at uni, and everytime I tried to login on Windows, it would crash underlying LDAP server, logging everyone in the classroom out and forcing ICT to restart the server.
