Your running into some of the problems in dealing with non Unicode character data. I would not trust any of the functions you have been using with any character above CHR(127) as what is actually displayed to the user varies from font to font.

Once you know the codepage and font you are using you can create your own look up tables and use chrtran() to evaluate the characters.
