Bug 23046 – RTL - forward delete key removes Hebrew letters and diacritical marks together.

• Component: HTML Editing
• Status: RESOLVED WONTFIX

[Jeremy Moskovich]

Chrome bug: http://code.google.com/p/chromium/issues/detail?id=5930

* Type (u05D0 + u05B1) into an rtl-aligned text input field in WebKit* e.g. the search field at http://google.co.il.
* Move the cursor to the start (right side) of the text.
* Press the delete key.

(*) doesn't work in ltr-aligned fields due to another issue: https://bugs.webkit.org/show_bug.cgi?id=23045

Expected Results:
* Only the letter Aleph should be deleted, the diacritical mark should remain.

What happens:
* The diacritical mark and the letter are deleted as one unit.

Both IE7 & FF3 behave correctly here, deleting only the letter and leaving
the diacritical mark alone.

http://trac.webkit.org/changeset/39169 fixed the same issue for the backspace key.

The behavior as described is compatible with the Cocoa text system on Mac OS X. Perhaps this is a platform-specific bug, but then the OS field in this report is wrong.

Makes sense, changing platform to Windows.

Does it mean that on Mac OS X, ICU's character iterator is not used for this in Webkit?  ICU's character iterator treats a sequence of 'base + (a) combining character(s)' as a unit and I thought that was to blame. (see also my comment at http://crbug.com/5930) 

BTW, what does the Cocoa text system does for a Latin base letter + a diacritic mark and 'delete'?

The letter and the diacritic are deleted together.
