[oXygen-user] (Resent with a smaller attached PNG screen shot) Is there a known problem for the display of Tamil with Oxygen on a Mac?

[Oxygen XML Editor Support (Radu Coravu)]

Dear Jean-Luc,

This looks like a problem of finding the right font to use for rendering.
 From what I tested on Mac, going to the Oxygen Preferences->"Fonts" 
page and using "Arial Unicode MS" both for the "Text" and "Author" pages 
seemed to properly render those letters in both pages.
In order to avoid end users needing to change settings in Oxygen to make 
this work, as you seem to have your own CSS for the Author visual 
editing mode you can define in that CSS a fixed font to be used for all 
the content,
something like:

> :root{
>  font-family: "Arial Unicode MS";
> }


Regards,
Radu
