EBCDIC
As one final point of interest, different countries have different character requirements, such as the á, ê, and ü characters. Due to the fact that IBM sold its computer systems around the world, it had to create multiple versions of EBCDIC. In fact, 57 different national variants were eventually wending their way across the planet. (A "standard" with 57 variants! You can only imagine how much fun everybody had when transferring files from one country to another).
