unfortunately your problem will not be solved by fixing this issue and
by inserting these Unicode control characters.
Why not?
Because these control characters will not change the order of RTL
characters. It will only change the order of text portions in BiDi
paragraphs.
An example, lowercase means LTR, uppercase RTL characters:
If you type(or import) “abcDEFghi”, you'll get in OOo: “abcFEDghi”.
If you put the LTR control character at the beginning of this
paragraphs, nothing changes, because the default for OOo is already LTR.
If you put the RTL control character at the beginning, you'll get
“ghiFEDabc”.
OK, I do not know all the theory that is behind it, but the empirical
test with the WP6 Arabic (13).odt attached to issue 51400 are giving me
following:
1) If I remove the control (whether there is space or not between the
characters, it means whether their are in the same word or not), they
are rendered naturally, RTL for all except characters 48-57 that are
numbers which are normally rendered LTR even in Arabic.
2) When I put the control back, ALL characters are rendered LTR. Again,
being inside the same word or not does not matter.
There are three types of LR/RL unicode controls:
a) Left-to-Right Mark (U+200E) and Right-to-Left Mark (U+200F);
b) Left-to-Right Embedding (U+202A) and Right-to-Left Embedding (U+202B)
c) Left-to-Right Override (U+202D) and Right-to-Left Override (U+202E)
Empirically the group (c) seems to be doing exactly what I needed.
I don't see a solution for your problem without reordering the
characters inside the filter :-(
I hope that what I wrote above is true, since this solution would be
much more difficult ;-)
Please correct me if I'm wrong, Frank.
Regards
Andreas
