I'm new to this mailing list, and to unicode.
I develop a Bidi/Unicode library for the .Net environment called NBidi (
While running test cases, I found problems regarding control characters.
I'll only ask about one scenario in this post.
The problematic test case is as follows:
Given text: <RLO>abc<PDF>
What should I expect as a result? My expectation would be (visual, control
characters removed) 'cba'.
If I leave the control characters in place I would expect: <PDF>cba<RLO>
The actual result I get is <PDF>abc<RLO>. This is because of:
Rule X4 sets the embedding levels to: 11111
Then rule I2 sets the embedding levels to: 12221
When performing reordering we get: <RLO>cba<PDF> ==> <PDF>abc<RLO>
Am I missing something here?
Thank you in advance,
