And it gets worse if you have to support multiple languages. If the company is in North America, they can probably get away with supporting 3 different languages (spanish, french and english).

If the company in the EU, there are 24 official languages at last count: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Irish, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish and Swedish.

You might get away with supporting fewer languages in some private sectors, but if you are running a government system (or a system that wants to receive funding from the government), you might have to support all of those. And as anyone can imagine, a "bad" word in one of those languages might be a standard word with a different meaning in another language.

Plus, even for countries speaking the same language, there might be big cultural differences. For U.S. citizens, a "tea party" means throwing valuable cargo into the harbor because they endorse "taxation without representation" but want to keep all the taxes for their own government(*). For Brits, it means "5 p.m."
