MVDs now support any text encoding. I've used ICU, the IBM-supplied conversion library for to/from UniCode conversions. It's very good. So texts may now be added to an MVD from any textual source. All you do is specify the encoding. Internally, merging is done on 16-bit UTF-16, not 8-bit UTF-8 any more. I don't believe any rival text-comparison programs can do this. This is a big improvement over the previous version of nmerge.
