The Text Find / Replace action doesn't work for unicode files. If I (manually) save the file in ANSI format, the Text Find / Replace action works okay. For unicode files, the action says 'no matches were found'.
The file which needs to be processed is generated by Visual Studio (.inf file for CAB); I don't think I can tell Visual Studio to generate an ANSI file...maybe I should try to read the whole file and then save it in the hope that the format will be changed to ANSI by FinalBuilder....
