These two patches are the long running work I have been doing to improve
complex script support in the edit control.  Please apply them and try and see
if there is improvement.

patched wine - bug with matra+characters - text document in the video

Notepad with patched (usp patch1 and patch2) wine 
http://www.youtube.com/watch?v=TwesTEMN1lM

notepad: normal and combined text is ok. but combined characters with notepad
is not.

wordpad: same old behavior, normal and matra text is ok, but combined is
causing cursor gap.

The patches seems to affect only notepad, and not wordpad.

wordpad with the pacthed wine git (patch1 and patch2)

Yes,  WordPad is a RichEdit control and I have not started work on the RichEdit
controls yet.  Just the Edit Control. 

So for now these patches will only affect Notepad.  Once we get them worked out
then It should be the next step to work on the RichEdit Control.


I see the issue with the mantras.  Overall is this an improvement or have we
just traded composed characters being off with mantras being off?

thanks!

I seems the latter, matras are being off.

before the patch:
I think that 'composed characters' gap happens due to 'halant' character. So,
It would be nice to - do the gap-removing with 'char+halant+char'combinations
only, as character *space* of halant (् ) stays/rendered in ligatures (द्व क्र
त्व etc.), hence there comes extra space. It was not happening with other
matras ि ी ु ू े ै ो ौ ॆ ॊ ॉ ॅ.

After patch:
only matras which are positioned on the left or the right sides of a character
(i.e., ा ि ी ो ौ ॊ ॉ) are causing the gap. Top and bottom matras are fine
(i.e., ु ू े ै ं ँ ॆ ॅ)

So, please choose the way whichever is easier for you. Thanks.

Well the hope is to be able to fix both. :)
It is just my needing to get the cursor positioning correct for Indic
languages.  I believe Indic languages do not allow cursors to position inside
of composed glyphs (unlike arabic which does). I will work on correcting that.

Ok, I have done a bit of work with indic clusters and handling cursor
positioning.

You can test Notepad using just the one edit.patch

Hopefully that improves cursor positioning.

There is still work to do as I need to properly group whole syllables into
clusters but this should at least improve things.

This will not affect wordpad.  Just notepad.
