Well, first, I don't know how to make those funky accent characters without having to look up the character codes. Second, Armmonia isn't really important enough for Garin to learn how to spell their name. I've been known to have some of my characters purposely mangle the spelling of other characters names from time to time. Taylin, on FEI, would spell one particular character's name a different way each time, even in the same letter.
Well you should spell it like how it is in the statistic page, Armonía
