Any ideas on how to solve this issue? The rendered PDF document is subsequently bad. I've tried taking Leelawadee UI (font) that Microsoft Word is reporting as the font and including it into the document.

Did specifying the Leelawadee UI font help? We can add a reference to this in the default fonts.css file in future releases.

It did not help, I've added Leelawdee and Khmer and have not been able to resolve this issue. Your help is appreciated, thank you!

***SOLUTION***

Adding this to prince fonts.css works:

@font-face {
    font-family: serif;
    src: prince-lookup("Khmer")
}

@font-face {
    font-family: serif;
    src: prince-lookup("Leelawadee UI")
}

We have now added Khmer fonts to the default font families in the latest builds, and also the Noto font family for all scripts if it is available.

Thank you!

This change has been backported to Prince 15.4.
