    Make CppunitTest_svgio CPPUNIT_TEST_NAME=Test::testCssClassRedefinition robust

Changed the font from generic Sans to Open Symbol to avoid failure when a
different font is used, but it didn’t change the text string to a one
supported by Open Symbol, so font fallback would still make the test
fail. Change the text string to “012” which is supported by Open Symbol.
