I've use VStudio Pro for a while. Usually with Thai locale and characters. Most of them work very well esp Thai sorting.
But one thing that really make report not quite correct is how it display the vowels characters incorrectly.
From the attached image, the left hand side is the report preview in HTML format. Look at the green arrow, the ligature feature (from unicode font) work correctly. it pull the vowel character down one level.
On another hands, the right hand side is the report preview in PDF format. The red arrow show the vowel character "float" incorrectly. And in some font, it just always pulled down and may overlaps with other vowels.
What I really looking for is to see the PDF preview work correctly like HTML one.
This problem is applied to embeded report tool (I tried with Xojo only)
Also, it should be the same problem if you test with other feature in some languages like "f + i --> fi" , "a+e --> ae"
