> western alphabet?
It is hard to say what is "Western" alphabet. Czech alphabet is as western as English, so is Swedish, Hungarian, Polish, France, Turkish... even Bulgarian or Greek which have totaly different layout of letters. So it is much more then 256 chars and that's a problem. You cannot skip any language becouse there are institutions like EU which consider all these languages equal and they want to use several languages inside single document.
You was just lucky enough. ASCII chars are 0-127 and "Umlaute u" you mentioned is naumber 129 in many codepages. So, it happens that in several codepages it is u but in some countries it can be anything else depending of codepage used. Codepage is the way how these chars (128-255) are interpreted. In Czech Republic we have many codepages, among others old "Soviet" style KOI codepage, Kamenicky (also obsolete), Latin-2, ISO, Windows-1250 to name a few :-). So we even have czech -> czech text file conversion programs.
