Good morning. I'm sorry that I bother you all once more with the same thing as a half year ago, but I was unsuccessful. So: How works the mechanism that sort items for the index? I have to write down my own sorting system for the Czech language. (Mr. Hagen sent me some files for customizing the ConTeXt for the Czech language, but it didn't include index sorting.) Well, I would appreciate some example, since the task is not so easy. In the Czech for example `a' and `acaron' go under the same item `A', but `acaron' is sorted after `a'. On the other hand, `ccaron' has its own item in the index (under the item for `c'). And to be even more complex, `ch' is one letter in the Czech, having its own item in the index. Many thanks for any hint. (And one more apologize for bothering you once again.) Michal Kvasnicka
