DM		 3 FIXME: Can someone provide a transliteration of this name into ASCII?
4 Using the following chars caused a compiler warning on HIUX (so I replaced
5 them with octal escapes), and isn't useful without an understanding of what
6 character set it is.
7 Written by Metin G. Ozisik, Mimi Ph\373\364ng-Th\345o V\365,
8 and John Gilmore.
