When trying to export characters such as those from the Chinese, Japanese or Korean languages in your PDF files, by default most of them will be replaced with little squares, as they are not supported.
To add support for these languages, simply log into the Admin Area and navigate to Settings and once the page loads click on the Account link. There you will find an option to change the export font to ‘Arial Unicode MS’, which will allow support for more characters.
Will all characters and languages work?
At the moment, not all languages are supported. From our tests on languages such as Russian, some characters are not supported by Arial Unicode MS.
Unfortunately we have not been able to test them all, and cannot guarantee they will all be supported. But from our community feedback, we have not had any reports of characters not working to date.
