Improve Maven build robustness

* UURIFactoryTest.java
    specify stirng literal with escape-encoding, rather than as raw UTF-8
* **/pom.xml
    include 'project.build.sourceEncoding' property to suppress platform-encoding warnings
    (unfortunately, neither this nor similar 'maven.compile.encoding' property actually casues maven build to interpret Java source as UTF-8)
