Have quickly name-changed for obvious reasons.
I'm called Lotte, after Lotte Lenya, but my parents decided to pronounce it Lottie, as it would be easier for people, and there really weren't any around, even the Charlottes were using a different diminutive back then.
No one (almost) pronounces it Lottie, it totally stumps people, they all stumble over it, and either don't bother and just ask how to pronounce it, or they pronounce it Lot. Then when I say it's pronounce Lottie, they all look relieved, and the rewrite it with an I. No, no, there's no I thanks.
It wasn't until I went to university and there was studying linguistics with lots of European, well travelled professors that people started to call me Lotta. And they didn't even ask, they just assumed, and that's fine with me too.
I do actually have German family, and I speak German, and I love how it's meant to be pronounced, so these days I answer to both Lottie and Lotta. My favourite people are my German and Scandinavian friends who pronounce it Lotta, which I love.
So, in summary, I love being called Lotte, it's really unusual and people tend to remember it. But, people will spell it wrongly, with an -a if you pronounce it Lotta, and with and an -i- if you pronounce it Lottie. Unless you cultivate some Norwegian friends, who are often overjoyed to find a "Scandinavian" name in England the only pronunciation I don't like is "Lot". Unless I'm being called it for short, 'cos Lotte's a very long name you see
Also, every new person will look at it and ask "is it short for Charlotte?". I met one woman who refused to call me by my name as she "didn't believe in nicknames and only used full names", thanks, but that is my full name; I had to threaten to get my birth certificate. And for lots of official-type paper work, people do tend to do "no, we need your full name".
But you get used to it, and I think it's worth it not to have been another Louise or Emma
