A similar problem happens when the name itself is only considered offensive in certain cultures, but is completely benign in the culture of the person with the name. I remember two gaming related incidents where people were blocked from making accounts; one was a south american using "negro" as his username being prevented from creating an account, even though english speakers with the username "black" are fine; the other was a muslim with the first name "Jihad" who couldn't create a playstation account. A muslim coworker told me that "jihad" being synonymous with "holy war" is pretty much just a western thing, it could also be referring to an internal struggle, so it's similar to christians naming a child "Chastity".
