These are the official correct Danish spellings of the lovely girls-name Majbrit:
Mai-Brit, Mai-Britt, Maibrith, Maibritt, Maj-Brit, Maj-Brith, Maj-Britt, Majabrith, Majbrit, Majbrith, Majbritt, Majbritte, May-Britt, Maybrit, Maybrith and Maybritt.
All the ones with an "I" or "Y" instead of "J" I find kind of annoying, but they are not really designer names. It's not like Shaqueenshaqa (pronounced Alexandra) which is just silly.
I don't think you can give a child a designer name here though. I remember a case where a mother couldn't name her son Kristophpher a some years back because "phph" in a name looks silly.
