Well I was able to come up with a temporary work around, but it's such an
ugly hack I'm almost embarrassed to share it!
I figured what I needed to do was force javascript to evaluate the String
somehow. Here are the steps I took to make that happen:
1. Use javascript control codes (as text) in your content (EG: \u201C)
2. Create a JSONObject with the loaded content
JSONObject json = new JSONObject();
json.put("content", new JSONString(response.getText()));
2. Serialize the object into a json String, and unescape the control codes
//note: StringUtil.unescapeJavaScript is a re-implementation of
// org.apache.commons.lang.StringEscapeUtils which uses a
// StringBuilder rather than a Writer. I can post if desired.
String data = "[" + StringUtil.unescapeJavaScript(json.toString()) + "]";
3. Evaluate the JSON string back into a JavascriptObject using a JSNI
native method
panel1.getElement().setInnerHTML(evalContent(data).get(0).content());
private static native JsArray<ContentMemento> evalContent(String jsonStr)
/*-{
return eval(jsonStr);
}-*/;
class ContentMemento extends JavaScriptObject
{
protected ContentMemento()
{
}
public final native String content() /*-{
return this.content;
}-*/;
}
Presto! I now have unicode characters in dynamic text content. However, I
would still really really love it if anyone knows of a way I can evaluate
the String data without having to go through JSON
Thanks again!
