Thai text will not export/print correctly even if Publisher is display correctly

[T.E.]

Hi,

Im using publisher 2.4
I Found that Thai text will not export/print correctly even if Publisher is display it correctly.
From screenshot below
I use 3 different fonts to test word "น้ำ"
Publisher itself are able to display it correcly in most of case
but when it come to export or print it will not produce what it seen on the app.

Perhaps this is (or is related to): https://forum.affinity.serif.com/index.php?/search/&tags=AFD-1907 ?

It might related, most of other problem that already reported are in the App itself
in my case,
it look like Publisher are able to display it correcly most of font are display in App perfect and correctly,
while some other font will will have just a minor problem (character stack in incorrect order but it readable)

but problem come when print/export most of stack characters moved to wrong place or on top of other character.

If I Convert text to curves or Rasterize layer
Publisher are able to print/export correctly.
but that would make my document uneditable.

This may also be because the Kedamee keyboard is inconsistent with the  ำ vowel because it needs the tone mark before the vowel to display correctly. This is inconsistent with the way we would write it with consonant+vowel+tone mark.

[T.E.]

If we type in consonant น +vowel ำ+tone  ้

most of app will put vowel in the wrong places like this นำ้  (correctly it should be  น้ำ)

(Except MS Word that would fix vowel position automatically)
