Why is this incorrect? should it be:

<rtl text>: 25 (USD)

?

Good, this is the only case we have tested.

You are seeing mirrored, LTR text.  Currently we are not expecting mirroring to be enabled.

You are seeing mirrored RTL text.  The text is being drawn in fragments, which are arranged RTL, but then SWT flip-flops the locations to their mirrored positions, giving the the above result.  We are working on supporting this case.

4 should be simple to fix.  I'm still worred about 1 though.  If 1 is working and 4 is fixed, then 3 will work too.
