Try the latest version I just pushed to github. Apparently the $LANG setting in your environment can have an effect on the interpretation of source files; I corrected this by setting an explicit encoding which should solve the problem.
Make sure you clean your source tree with "git clean -x -f" before you try again.
Thanks for the report.
