I want to perform a simple analysis of some Greek text: collect the different words used and count their frequency. It seems that some of the built-in commands do not work well with Greek letters. For instance, with
words = StringCases["α β1 rpr other", WordCharacter ..] (where I use actual Greek letters such as :a: - I didn't fix the copy/paste issue into the browser), the output is
{"1", "rpr", "other"} How do I get Mathematica to recognize other kinds of words?
