Unicode characters are lost when embedding JRuby even if the calling code
performs no conversion to byte[]
----------------------------------------------------------------------------------------------------------
Key: JRUBY-4890
URL: http://jira.codehaus.org/browse/JRUBY-4890
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.5.1
Reporter: Trejkaz
Assignee: Thomas E Enebo
The following tests fail on JRuby 1.5.1 if file.encoding is set to any value
which cannot encode Japanese characters (we discovered it with windows-1252.)
The Unicode characters present in the original script become "?????". As the
script itself is already a string and the code embedding it never converts to a
byte[], I believe that there should be no reason for it to convert anything to
the default encoding.
{code:java}
public class TestUnicodeCharacters {
String orig = "\u3070\u304B\u3084\u308D\u3046";
String scriptlet = "str = \"" + orig + "\" ; puts str ; str";
Writer writer = new StringWriter();
@Test
public void testCharacterEncodingViaScriptEngine() throws Exception {
ScriptEngine engine = new
ScriptEngineManager().getEngineByExtension("rb");
ScriptContext context = engine.getContext();
context.setWriter(writer);
String result = (String) engine.eval(scriptlet, context);
checkValues(result);
}
@Test
public void testCharacterEncodingViaScriptContainer() throws Exception {
ScriptingContainer container = new ScriptingContainer();
container.setWriter(writer);
// The next lines don't help anyway, but I half expected them to...
//container.setCompatVersion(CompatVersion.RUBY1_9);
//container.setKCode(KCode.UTF8);
String result = (String) container.runScriptlet(scriptlet);
checkValues(result);
}
private void checkValues(String returnedResult) {
assertEquals("Wrong result returned", orig, returnedResult);
assertEquals("Wrong result printed", orig, writer.toString().trim());
}
}
{code}
