thai stacking diacritics
Hi,
We're trying to produce some thai output with FOP but FOP doesn't seem
to be adjusting the diacritics.
In the following sample, there are two characters separated by a space,
the first character has one diacritic, the second character has two
diacritics. I'm not sure if it gets through the mail.
Anyway, the diacritics of the first character should be moved down to
the same level as the first diacritics of the second character
I'm using ArialUnicodeMS font but I also tried with TH Sarabun and
Tahoma. I tried several combinations of language and script but none
worked, so I left it with no settings in the sample. I'm using FOP 1.1.
One interesting thing I noticed, some "above the character" diacritics
can be stacked above other diacritics or not, whereas others can only
occur as first one (bottom one) of the stack. That's my understanding,
I'm not a thai speaker. In some fonts, the diacritics that can be in
several "above" positions come in the font in the high position. So if
they occur alone, they need to be adjusted down. That's the case in
ArialUnicode. In other fonts like Tahoma, all the diacritics come in the
font at the same "height", the low position, so when stacking, one of
the diacritics need to be move up.
Any idea if this can be made to work with current FOP.

Hi,
according to FOP complex script page [1]
Thai script is not fully supported in FOP 1.1.
I don't know if the complex script author (Glenn Adam) plans to add it
soon, but feedback is always welcome, and userland wishes can help to
determine priority of improvments.

I had no problem with this once I changed the font family name in your file
to read "Arial Unicode MS", in order to match the name in the arialuni.ttf
file. See the attached output. I've also tested Thai with the following MS
fonts:
Angsana New angsa.ttf
AngsanaUPC angsau.ttf
Browallia New browa.ttf
BrowalliaUPC browau.ttf
Cordia New cordia.ttf
CordiaUPC cordiau.ttf
DilleniaUPC upcdl.ttf
DokChampa dokchamp.ttf
IrisUPC upcil.ttf
JasmineUPC upcjl.ttf
KodchiangUPC upckl.ttf
Leelawadee leelawad.ttf
LilyUPC upcll.ttf
I'm using the current trunk build, but 1.1 should have no problems here.
