The purpose of this chapter is to provide a guide to the complexity of creating, managing and analysing a set of text files in languages using Greek and Cyrillic alphabets. It ought to be as easy to do this for Greek and Cyrillic as it is for English, since all the processes are in theory at least the same, and the only difference is the use of different alphabets. In fact the difference in the alphabets accounts for all the problems which justify this chapter.
