AW: ICU question with embedding levels

I solved the problem already.

This mail was sent twice due to problems with our mail server.
Sorry.

It is hard to tell exactly what your example is. Here is what I am
guessing.

Your input is (where AB are RTL characters, 0..9 are numbers, and " "
is space):

12 34 56 78 AB 90

You want the following output:

12 56 34 78 BA 90

The way you would do that is to use a RLO. An override will actually
change the character types of the characters it embeds, instead of
just changing the level. That will force the 3,4,space,5,6 to act like
RTL characters. So change your input to:

12 <RLO>34 56<PDF> 78 AB 90
