Uncertain project language encoding

[raidan2]

It is recommended to explicitly set encoding for project according to
https://maven.apache.org/general.html#encoding-warning

For instance, I even have

[WARNING] File encoding has not been set, using platform encoding Cp1251, i.e. build is platform dependent!
and could accidentally miss symbol not in standard encoding table.

Which encoding it should be? UTF-8 or good old US-ASCII?

[deruelle]

UTF-8 is preffered

[raidan2]

Then you have my PR: #152

I have added UTF-8 into a root pom by local commit. Thanks for your update. (#152)
