I create healthcare documents in a variety of languages that must be reviewed for accessibility for screen reader users before publishing. I have run into a problem with a document translated into Khmer (Cambodian) - this was created in Word and then saved as a PDF, but this problem is happening even when I create documents from scratch in Adobe. [I am using Adobe Acrobat Pro - version 2023.006.20380]
The font looks perfect on the PDF page, but in the content tool, the text in the containers is showing up interspersed with diamond question mark characters: �. According to my accessibility team, these characters will not be announced accurately by assistive technology - meaning we're stuck.
Thank you for any advice you can provide, this has been a frustrating roadblock!
Font is installed...
...but doesn't show up on this embedding list
The Khmer fonts are embedded in the document attached (Ctrl/CMD D ; Fonts)
It just looks like certain “modifiers” are not correctly shown. It's the first time I have seen Khmer text as this, so my observation may be utterly wrong.
We are also encountering the same issue. Any chance you/your team found a way to fix the issue? Please let us know. We are also using MS Word and when we create a PDF using the Acrobat 'Create PDF' option, we see the same output as the screenshot you have provided. But, if we create a PDF using the 'Save As' option, the diamond question marks will disappear but some characters will show up as dotted circles instead, which means the characters are still corrupted.
Also, the fonts are already embedded in the PDF but the characters still show up as corrupted. If you cannot find the font you used from the list, you can add it manually, the same as in the screenshot below. Unfortunately, this still doesn't fix the issue.
Thank you very much and hoping to hear some answers/advice.
