Re: another question about layout in ICU 2.6

Hi Jens,

I've been looking at the changes I've made to the LayoutEngine since ICU 
2.6, and I'm not sure that any of them address the problem you describe.

Can you please send me an example of a character sequence that is 
rendering incorrectly? Also, let me know if you see the problem with all 
Khmer fonts, or only certain fonts. I'll see if I can figure out what 
other patches you might need to make it work.

One major change I did since 2.6 was to implement the Multiple 
Substitution subtable - it's possible that this is somehow related, 
although this code is not hit in ICU 3.2 using the Khmer samples and 
fonts that I have.

Regards,
Eric
