UTF8 and Unicode text file formats

I have recently realised that some users processing Russian, Bulgarian etc. may not be getting suitable results because they do not know that WordSmith won't be happy with UTF8. (This is a text file format which doesn't necessarily use 1 byte per character.) I have been working to get WS5 to detect files in this format and automatically compensate, preferably re-saving the text file in 16-bit Unicode.
