#2102 can't correctly mark Hebrew text in tk entry/text widget

[dingjun]

I use tcl/tk 8.4.6 to develope a programm with GUI.
When our programm runs under windows XP Professional
with SP2, und user tries to mark some Hebrew text in
the entry/text widget, the marked texts shift
themselves always. Under Linux (kernel 2.4.21) man can
mark some Hebrew text, but the Hebrew text is not
correctly displayed and the writing direction is wrong.

I think this has something to do with the writing
direction from right to left of Hebrew. I have tested
my program with Arabic, an it has the same problem. So
it may be a bug in the implementation of entry/text
widget.
It's would be great, if this Phenomenon can be located
and fixed in a patch.

Certainly won't be done in 8.4; 8.5 has a near total rewrite
of the internals of the [text] widget so effort from one is
not reusable with the other.

I've no idea how much effort it would take to get into 8.5;
we've never grasped the nettle of writing direction before
as far as I can tell.
