The thing that makes me wince, and I apologise if anyone here has, or has kids with bizarre spellings of regular names. I've met a Serah (Sarah), Liesa (Lisa), Natashia (Natasha), Krystyna (Christina) and on the other end of the spectrum I came across the name Leah which was pronounced Laya - I don't know what these alternative spellings serve to do, other than to confuse the reader and irritate the person who's constantly having to correct other people.
Although I must say I also wince when I see names spelled differently to the norm..eg, Aimee, Chelsee, Symon at least you can actually tell how the name is supposed to sound.
