Managing the canonical representation of your name in my system is one of the few things you are responsible for.

The number of times I have had people ask me to customize name rendering, capitalize things, trying to build phonetic maps, all of these things to avoid data entry or confusion and all they do is prove out that you can't have a general solution to human names, you can hit a big percentage in a cultural context, but there's always exceptions and edge cases to the problem we're solving which can be described as "please tell me your name when you call or whatever so I can pronounce it right"
