Flex special character escape

Many flex applications add the "" symbol at the bottom, and some special characters are required in many cases. However, it does not seem to work normally if "& copy;" is used simply. The following example lists the numerical encoding of most special characters, which can be conveniently used in flex. In the demo, double-click a row in the DataGrid to display the character and number encoding below and copy the data directly.

Let's take a look at the demo (You can right-click View Source or click here to viewSource code):
