My new name doesn't have a middle name yet, so I'm accepting suggestions on what I could adopt that'd break as many systems as possible.
Obvious answers:
* null
* an emoji
* U+FFFD οΏ½
* half of a unicode surrogate pair
* EICAR
* some kind of prompt injection
* the entirety of DOOM, base64 encoded
* an illegal prime
* the source to decss
