In this case, Babelfish has worked quite well, since I'm only translating short phrases (comments). I'm just trying to shortcut the process of opening source files in Word then copying and pasting into IE, the combination of which is the only way I've successfully fed the Shift-JIS from the source files to Babelfish as UTF-8... Perl seems like the perfect tool for this job.
