*** Issue 89974 has been confirmed by votes. ***

I confirmed this is a significant issue that really needs to be fixed for Thai
people.

SBA: With the correct fonts installed, I have no problem on WinXP (SP2), neither
with OOo 2.4.1 nor with current OOo 3.0 RC1. Display and printout look fine.

SBA->smackoz: Please re-verify your (K)Ubuntu findings with OOo 3.0 RC1 or
younger and comment here. Thank you.

SBA->ES: (K)Ubuntu/Linux Font installation? Fontcache? AFAIK the font handling
changed on all Linuxes for OOo 3.0. Please proceed, thx.

Set to "Worksforme". Put HDU, FME and myself on c/c.

.

To confirm again, I rechecked on Ubuntu 8.04.1 with OpenOffice.org
1:2.4.1-1ubuntu2. The problem is not solved in 2.4.1 yet.

Recheck with OpenOffice.org 2.4.1-ubuntu2 on Ubuntu 8.04.1.

In the following screen caps, I put some highlight on 
the incorrect rendering in Angsana New 
(rendered with Waree, I think?) against Norasi (in cap1), 
and Arial against Garuda (in cap2.  
(For Lucida Sans and Times New Roman,
I think it's clear the rendering is incorrect.)

Please see:

I use OO on ubuntu 8.04.1

SBA: OOo 2.4.1 is released.

Again: What are the findings with the Office that is actually being worked on? 
-> Please visit http://download.openoffice.org
-> Download a current Developer snapshot or Release candidate (OOO 3.0 RC1 is
available)
-> Install it on the same system you found the problems with
-> Re-verify your findings
-> Comment here.

Thank you.

I have tried OOO300m5 build 9350 and this problem has gone. Anyway, 3.0.0 will
not be included in Ubuntu 8.10 which will be released next month. That means we
may need to wait around 6 months to get OOo work by default after installing
Ubuntu and also other distributions.

Is it possible to point us to some patches for backport?

The fixes for issues 89262 and for issue 88376 probably solved this problem here.
If Ubuntu needs to stay with OOo2.4.1 I really recommend that they integrate these fixes into their build.

Here are the minimal patches for the backport:

If you check this issue by using the test document attached with OpenOffice
3.0.0rc1 20080904 you will see for yourself how this issue is NOT yet resolved
for OpenOffice 3.0.0rc1 20080904! Rendering / Printing Errors still exist for
some Thai fonts. Garuda and Norasi are two notable examples. Are there others?

Well, I think we have here different problems (printing, rendering) so that they
should be treated separately.

I will only treat the rendering problem here.

I has a look at your last attachment: "Thai Langauge rendering Test Doc 03.odt" 

Test environnement: with OOO300m7 on Ubuntu 8.10 alpha.
Fonts present in the document and on my system:
- Garuda   
- Lucida Sans
- Waree
- Norasi

Fonts present in the document but NOT on my system:
- Arial
- Angsana New
- Times New Roman

Your problem: Though you wrote "correct/incorrect" I guess we can express the
problem with: the diacritical signs of some letters are sometimes not placed on
the letter, sometimes crushed together. Is that correct?

My results: At anytime I could reproduce the rendering problem of diacriticals
as it shows on your screen shots.

NEEDMOREINFO:
- Please send me by mail all the fonts listed above which show the problem.
Write the issue number in the subject line.
- Test if this rendering problem does/doesn't show *with the same fonts* in
other non OOo application (Text Editor, Mailer, other word processor)

of course I meant: "at NO time I could reproduce..."

Waiting for information.

I can give the exact problem explanation here.

The real problem is sara-um, "ำ". This character consists of 2 parts which one
of them must be rendered on previous character, e.g., "อำ". This problem will
occur with upper character after sara-um for example "่" in "ตำแหน่ง".

One thing I can notice is that it seems this problem only occurs with
distribution specific binary. Note that it occurs on many distributions
including ubuntu and mandriva. However, there is no problem for binary from OOo.
Other applications on ubuntu has no problem like this.

I will try to send all fonts to you. Hope my guess of your email is correct.

> it occurs on many distributions including ubuntu and mandriva. However, there is no problem for 
binary from OOo.

Now that is interesting. The difference between the builds is that the ICU-version used in OOo-builds 
is patched, while the distributions prefer the straight version. To fix this problem they probably 
shouldn't build with "--use-system-icu" unless they are sure that their system-icu is better.

Though OOo's layout code could easily handle newer versions of ICU's layout engine, so that the 
corresponding system-icu wouldn't need the patches, other parts of OOo still depend on specific 
versions. See issue 84683 for the khong's progress on that frontier. 

> Other applications on ubuntu has no problem like this.

I suspect that all applications that use ICU for layout (instead of pango) have the same problems with 
the same fonts.

Correction to the above: issue 86483 is about the using the newer version of icu

"There is no problem for binary from OOo"

So we can close here.

Sorry for the slow reply.
I'm confused by the latest responses from sugree and es.
Am I missing something because the formatting errors I have listed as examples
have been generated with the OOo binary on Windows XP NOT Linux.

I am also confused because:
- 2 (smackoz, sugree and more) people reported different problems. Sugree's
problem is solved as "WORKSFORME"
- smackoz: you say it happens on Windows, not Linux but in your first comments
you talk about Ubuntu and the screenshot is on Linux... so what?
- Not all the "problems with Thai fonts" are the same problem.

So please be clear:
- which font on which system makes which problems? Send me the fonts and
*describe* the problem (not only with screenshots)
- also check in other applications what happens *with the same font*: the linux
screenshot shows a wrong rendering in OOo compared with a correct rendering in a
dialog box. Yes but it is not the same font.
- at best, reopen a new issue with all the needed info. This one is too confusing

OOo 3.0 RC1 Windows XP. You can see from the newly attached images where the
problem occurs. The tone marker ้ over the ำ and the tone marker ่ seem to cause
alignment errors with some fonts on Windows XP.

OOo 2.4.1 Kubuntu 8.04. Here the rendering of the fonts seems to be more
problematic. The vowel เ and the tone markers ้ and the ่ are not rendering
correctly or seem to be causing rendering errors with more of the sample fonts
or is it something else?

Will test OOo RC2 on Kubuntu and Windows XP once I've downloaded the binaries.
Does this help to identify the cause of the problem?
If you need copies of the fonts for test purposes let me know.

See more comments left...

@smackoz: yes please send me the fonts you are using and confirm that other non
OOo applications DON'T have this problem when using the same fonts.

Does the problem only happen when sara-um is present? This characters is
specifically treated by ICU, with some reordering, if I remember well.

@javiersola Yes, sir. Only after sara-um.

This is a serious bug for Thai. Anyone working on this? need more info?

Windows 7, AOO 4.0.1, Build:9714 - Rev. 1524958

Running the test document still created rendering issues for Lucida Sans.
