At the recommendation of another post, I ran the program with the following commands, all to no avail: Code: LC_LANG=km_KH wine theword.exe LC_LANG=KH wine theword.exe LC_LANG=kh wine theword.exe LC_LANG=km wine theword.exe LC_LANG=km_KH@utf-8 wine theword.exe None of them worked. If Wine supports Unicode, why would this not work? Just a note, the interface of this program is not Khmer, but a module within it is. Any other advice?
