Weird, the actual serbian word is "čuda", pronounced "chuda", and they're completely ignoring the diacritics.
For example I think most people will write the name of the car make Škoda as Skoda.
Hypothetically, and with a little exaggeration to make the point, if Sweden had somehow had that global influence in the mid-20th century, the American actress "Raquel Welch" might have been stuck with "Rakuel Velch" in her passport, and Swedish people would wonder why she was annoyed by this.
