In IRC, U's and V's apparently look identical.
I sometimes use "Uira" for reasons I won't get into here, and someone once asked me if Vira was plural for Virus.
Not to mention the ten thousand times I get "Uriu". My own grandmother, God bless her, went to put it on my birthday card, but couldn't remember which way it went... so she asked my mother, who got it wrong. Grandma was gonna do it right, too.
And nobody knows how to say it either. The only guy I know who has four letters who cause more trouble than I do is named Xjph.
