It's in your interpretation/the writing in the FAQ.

It should be more like "Why does setText(" ") not output a NO-BREAK SPACE
character into the XML document".

There is no difference in Java between "&test" and "\u0026test", except that the
latter is harder to read. Both translates into the exact same bytecode.

The FAQ could be complemented with the corrected call, e.g. setText("\u00a0"); To make
things more confusing Java uses hexadecimal code units while XML uses decimal code points.
