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 �
* 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
* 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0

@foone I chose null (i.e., to delete my middle name)

This has broken many systems and call center operator brains

If you wanted to make a choice that broke the maximal number of systems that wasn’t just blank, choose a name with at least three space delimited tokens and which is possible to say over the phone. e.g., Alice Correct Horse Battery Staple Averlong. You will then see what badly designed systems decide to split on what word for the last name.

@ZiggyTheHamster my previous name's Entirely Normal Middle Name apparently broke a lot of systems, actually: my driver's license has my name as "FooneMIDDLENAME Turing", but only on the digital barcode on the back, the front has me as "Foone MIDDLENAME Turing"

This hasn't caused any issues yet, but it does mean every airline boarding pass I've ever gotten has been misprinted

@foone I don’t recall if there’s an AAMVA reason for this if you mean it is totally a normal middle name and aren’t using a euphemism

@foone @ZiggyTheHamster wait was your previous name actually MIDDLENAME or was it actually entirely normal?

Because I was about to suggest just Middle Name, if "people trying to figure out whether you broke their system" counts towards the goal.

@virtulis @ZiggyTheHamster yeah, it was something normal that I don't want to reveal for deadname reasons
@foone @virtulis very odd they wouldn’t put a space there, then!
