Bug 47171

(*** This bug was imported into bugs.kde.org ***)

Package:           kword
Version:           1.2rc1 (using KDE 3.0.3 )
Severity:          wishlist
Installed from:    RedHat RPMs
Compiler:          gcc-2.96
OS:                Linux
OS/Compiler notes: RedHat 7.3 KDE 3.0.3 (official RPMS) KOffice 1.2rc1 (from RPM)

Preamble:
=========
To denote Hebrew text I will use 2 Hebrew words "SHALOM OLAM" which meens "hello world".
When indicating text entry I will use the Latin ordering i.e SHALOM OLAM.
When indicating text display I will use the Hebrew (visual) ordering i.e. MALO MOLAHS.

General Description:
====================
The paragraphs language follows the general paradigm of paragraph order i.e. the first non-neutral character determines the paragraph order and there is no way for the user to override this behavior.
This Itroduces the following problems:

How to Reproduce:
=================
Using Israeli keyboard layout and Hebrew fonts (iso8859-8-i) with kword:

The simple case (no punctuation):
---------------------------------
so writing:  hello world SHALOM OLAM
produces:    hello world MALO MOLAHS

and writing: SHALOM OLAM hello world
produces:    hello world MALO MOLAHS  
as well (only the default justification is different).
  
This problem is compounded if we use punctuations:  
Writing:     hello world! SHALOM OLAM!
produces:    hello world! MALO MOLAHS!
(note that the only thing wrong with this picture is the right-most '!' sign.)

Writing:     SHALOM OLAM! hello world!
Produces:    !hello world !MALO MOLAHS
(note that now the only thing wrong with this picture is the left-most '!' sign.)
  
Justifying the text to the right or left does not alter this text ordering.

This behaviored seems perfectly good for a simple text editor will just won't do for a full fledged word-processor.


Expected Behavior:
==================
Let's introduce a new notation:
<H>   denotes an invisible RTL character.
<E>   denotes an invisible LTR character.

The simple case (no punctuation):
Writing:     <H>hello world SHALOM OLAM"
Produces:    MALO MOLAHS hello world

Writing:     <E>SHALOM OLAM hello world
Produces:    MALO MOLAHS hello world

The complex case (with punctuation):
The neutral characters following LTR character should be LTR
The neutral characters following RTL character should be RTL
with no regard to the paragraph ordering and so:

Writing:     hello world! SHALOM OLAM!
or writing:  SHALOM OLAM! hello world!
Produces:    hello world! !MALO MOLAHS
(note that the default justification will be different)

Writing:     hello world! SHALOM OLAM<E>!
Produces:    hello world! MALO MOLAHS!

Writeing:    SHALOM OLAM! hello world<H>!
Produces:    !hello world !MALO MOLAHS

The user should have the following controls (via keyboard and toolbar) Insert <E>/<H> at beginning of line. (see simple case)
Insert <E>/<H> at current position. (see complex case)

This mode of operation will be known to the Israeli user because MS-Word works simularly.
