The apostrophe thing isn't bad when it's not overused in a work and there's good reason and usage behind it. If they're just throwing scrabble letters onto a board and then using those syllables with randomly inserted apostrophes, then that's pretty annoying. If the words actually have some thought and conventions behind them, like how the Polaris do their caste system for naming (Mu'Randa, Bis'Andreya), then it's not bad at all. I personally tried other punctuation as opposed to the apostrophe, but it both looked a little weird and didn't quite indicate the kind of slight, barely perceptible pause the names were supposed to have... that and I didn't want to hear someone refer to one of my main characters in my novel as "Vera Dash Shan". That actually happened when I tried dashes. <_<
And since I mention her, she so far has the only name in my novel with an apostrophe, though the characters just refer to her by the first segment. Just a piece of trivia.
Some other symbols I've tried include " : ; . / | ~ ^ * _ and = Just look how weird it looks with those symbols: Mu"Randa, Mu:Randa, Mu;Randa, Mu.Randa, Mu/Randa, Mu|Randa, Mu~Randa, Mu^Randa, Mu*Randa, Mu_Randa, and Mu=Randa.
