Re: UI problems in editing BiDi texts.

[Hooman Mehr]

While we are at this topic:
As I already mentioned, I am working on Persian GUI spec document [1]. 
One of the sizable portions of this document deals with this topic. If 
somebody wants to quickly start working on a new and improved 
implementation, please consult me to share my experience and early 
draft on the issue.

Also, note that this issue is one of the single most important issues 
we need to solve in order to make using computers as easy for bi-di 
users as it is for Roman (or Latin) Script users.

There is a lot of depth to this issue, don't try to come up with a 
quick idea and immediately think that you have solved it. It takes an 
expert in human computer interaction design. Someone in the same class 
as experts like Jeff Raskin, Bruce "Tog" Tognazzini, Donald A. Norman 
or Jakob Nielsen. Even then, we need extensive prototyping and user 
testing to refine the solution and select the best alternatives.

Alright, I know, we don't live in an ideal world (or Iran) and we 
really can't expect to go after this issue in a really systematic way, 
but lets try to deal with it the best we can.

The problems appear when typing a text in a BiDi enabled editor. it
seems to three categories of concren.
1) When typing a bilingual text, the cursor jumps unexpectedly. An
example, is when I type "HERE IS SOME RTL TEXT", (where UPPERCASE
stands for RTL characters), in notepad or any input line, the cursor
(denoted by |) and text appear as follows:

Hi Ordak,

The message you sent is not complete, right?  And you know, this
problem cannot be solved without implementation.  Because the
Unicode bidi algorithm we are implementing is such a beast with
those things called "directional embeddings" and blah blah.  BTW,
please go on and elaborate, we get the idea.

Thanks
behdad
