If you are having problem typing Khmer Unicode in Illustrator, then this post will help to fix that. The problem I encountered was that the leg doesn’t appear after type ‘j’ and the vowel some time on wrong letter. Well anyway, basically, the problem is when you type it doesn’t turn out as it supposed to be. You need to do below settings. FYI: I’m using Adobe Illustrator CC.
Step 1: Go to Edit > Preferences > Type… Then make sure that “Show Indic Options” is ticked.
Step 2: Click on Paragraph link to see the paragraph dialog box then click on the little menu icon on top right of the dialog and make sure that the option “Middle Easter & South Asian Every-line Composer” is ticked.
With this you are good to go. 🙂 Enjoy typing Khmer in Illustrator. If it doesn’t work please drop a comment and mention your illustrator version.
