In this part of the world the name would be quite political. We only use the letter Č (pronounced as ch) but our neighbors also use Ć (pronounced the same, only softer.. it's literally called "the soft Č"). There are a lot of 1st/2nd/3rd generation immigrants from those countries and their last names almost always end with Ć. So "he/she has a Ć" became a rude way of saying "he/she is an immigrant". And spelling someone's name with a Ć when it's actually Č can result in a very heated argument. I have no doubt you could find developers who would refuse to work with Ć :)
