Can you tell me which file? There were problems at one point with character set corruption on the copyright symbol attacking the colt library at one point. The hot fix is to delete the copyright symbol from the selected file - the copyright statement must be left intact. Please provide me the name of the affected file so I can patch with an updated corrected copyright symbol in UTF-8.

I find the same problem on macOS Sierra.
There are a lot of files in /src use "windows-125" encoding.
I think UTF-8 is better, almost all OS such as windows, linux, macOS support this encoding.
I forked your project, and converted all java files into UTF-8. If you think is useful, please merge into your code.
