In a recent project, I wanted to load the Unicode
values for special
characters from an external XML file. I wanted these values to show up
in a label or text box using something like label.htmlText =
"\ul00A9", which would produce the copyright symbol. However, when I
loaded the values from a simple XML node, the resulting label showed
the literal value"\ul00A9" instead of the copyright symbol. I created
a test application and found that local XML vars work and local
Unicode strings work, but not loaded Unicode values from XML. I have
sample URL for my test application (right-click view source) and the
code below:

test1.htmlText = localXML.data;
test2.htmlText = "\u00A9"; // string
test3.htmlText = tempXML.data;
}
