Status: RESOLVED FIXED

(Core :: Layout: Text and Fonts, defect)

Description

[Maha Abou El-Rous]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows 98)
BuildID:    00000000 - Bidi build dated 20010404

Bidi: When a Arabic visual (FE range characters) htm is displayed on Windows 
2000 and windows NT having a 06 character such as kashida or Arabic semicolon, 
Shaddah in it, the system does some bidi processing to the string which then 
changes it correct order.

Reproducible: Always
Steps to Reproduce:
1.Open file cp864.htm
2.check out on of the words with Shaddah in.

Actual Results:  the order of the word with Shaddah character is mixed up

Expected Results:  the word should read correctly. You can view that by setting 
Mozilla clipboard mode to logical and copy that word, then paste it in Notepad.

Need to insert Right-to-Left markers before those characters in the buffer, to 
force their correctc display on Win2000 and NT

after talk to maha, we decide to change the 864 to unicode converter to solve 
this issue
We need to add 200E before the following code point

E0
AC
B0-B9
BB

I need to rewrite the converter, I cannot use the current .ut mechanism to do 
that.

Assigning Arabic bug back to mahar:

[e-mail]

Zach, in future, please re-aasign Arabic specific bug to her. You should
keep Hebrew or Bidi bugs.

Comment 16

[Maha Abou El-Rous]

the patch in bug 81664 solves this problem as it handles FE & 06 characters 
seperately and thus at one point of time there is only one type of string sent 
for display (either FE or 06).
