Encoding characters removed from tests.Rraw. They fail the grep in CR…

…AN_Release.cmd because they've failed on CRAN before. Reopened issue #469 and postponed it to v1.9.10 to resinstate these tests into DtNonAsciiTests package. Those characters cannot even be commented out because their presence in the file causes the CRAN issue. There probably is a better solution but I do not know it.
