Describe the bug

Write string array failed if it contains non-ASCII characters.

To Reproduce

            WritableGroup group = hdfFile.putGroup("group");
            group.putDataset("strings1", new String[]{"hello"});  // success
            group.putDataset("strings2", new String[]{"你好"}); // failed
            String[][] strings = {{"你好"}, {"世界"}};
            group.putDataset("strings3", strings); // failed
