Hi All,

I'm Working on Khmer InDesign File, Khmer Transaltion ready in Word File, So I copy Khmer text from Word then Paste into InDesign File. Finally I sent PDF to Transaltor for Proofreading, But transaltor told me that there are Many BROKEN WORDS (see enclosed Screenshoot), Any one Know How to fix it.

I appreciate your help,
