Hi, I have some ideas for how to do this, but it would be better (read: 
you would get more responses) to discuss this in a broader forum. I 
strongly suggest you subscribe to the icu4c-support mailing list and 
repost your question there. http://oss.software.ibm.com/icu/archives/

Viele Grüße,

        Subject:        ICU question with embedding levels 




Hi,

i am testing ICU 2.4 with your Layout sample.

But i have problems with embedded levels using the ubidi_setPara und 
ubidi_getLogicalRun API.

This is my sample in logical order.  <<12 34 56 78 90.txt>> 

12 34 56 78 AB 90

AB are strong RTL characters. Paragrapg level is LTR. "34 56" should be 
treated as RTL run

How can I achieve the following visual output:

12 56 34 78 BA 90

I tried 2 solutions

1. if i am using embedded levels ("00011110000000000") with ubidi_setPara, 
AB is not resolved as RTL run, when calling ubidi_getLogicalRun.

2. if i am using the RLE keyword (12 <RLE>34 56<PDF> 78 AB 90), the output 
is  12 90 BA 78 56 34

Please show me the right way.

I would be very glad, if you can help.

Thanks

Stefan Wanger
