cramtools-3.0/src/main/java/htsjdk/samtools/cram/lossy/Binning.java:61: error: unmappable character for encoding ASCII

Hi, I am not sure this is a cramtools issue but maybe an issue with htsjdk which you have bundled in your source tree? anyway, looks there are some UTF8 or whatever encoded-chars left in the java file. Java8 is too picky about these, even in comment lines. :(
