I'm informed by Thai speakers that the text is split into 4 lines, each character can have up to 4 elements stacked on top of one another. In InDesign documents the top line won't display correctly, it seems to merge with the mid line. I've tried changing the spacing etc but can't correct the problem. Any advice on this would be appreciated.
Try enabling Adobe World Ready Paragraph Composer in the flyout Paragraph menu.
Thanks so much Ellis home - this worked and has saved me a lot of hassle!
