[JGIT PATCH 1/1] Invalid test preventing a build using maven

[Constantine Plotnikov <constantine.plotnikov@gmail.com>]

I have tried to build jgit using maven on Windows and build failed due
to the failed test. The test
QuotedStringGitPathStyleTest.testDequote_OctalAll was dependent on the
system charset. If the test is run with -Dfile.encoding=Cp1251 under
eclipse, it failed as well.

This was cased that by the fact that corresponding test generated
invalid UTF-8 character sequence for code points U+80 - U+FF. In that
case the method RawParseUtils.decodeNoFallback fall backs to the
default system encoding that is Cp1251 in my environment.

The attached patch ensures that correct UTF-8 character sequence is
used in the test.
