Punctuation by Languages

Not too long ago, I was managing a translation project in Access (English to Greek) when I discovered that the translator hadn't used question marks similar to those used in the English source. Instead of question marks, he was using semicolons. I was sure that this was a mistake and that the computer was acting strange again. But it wasn't a mistake. In the Greek language, the question mark is like a semicolon, and the semicolon is instead a raised period. I've started to check on other projects as well, and I've learned quite a few interesting things about punctuation and their separators.
