As others have said, readers will pronounce the name however they want to mentally, depending on their own experiences and so on. If it's important to the story, you can absolutely have a scene with the correct pronunciation. One of Jo Beverley's books had a character with the last name Cave, said "Cah-vay," for instance.
I read one novel where the MC was named Gruoch. It's a Gaelic name and the book took place way back in Celtic Scotland, but the author introduced the name, had a line about how to say it, and proceeded to use a nickname for most of the book, presumably to stop herself from typing Grouch.
What's your character's name then?
I'm fine with odd names, as long as there are consonants, vowels, not too many syllables and it makes sense in context. After a lifetime with a weird name that's not even that hard to say, I'm impervious to strange character names. Besides, when you read silently, I'm not sure that pronunciation is really all that important, in the end. I read the word, know it's the character, and move on with the rest of the story.
