Viewfile Cannot Render Unicode Characters in PowerPoint Files
Symptoms
- Some UTF-8 characters, eg. Japanese are rendered as boxes when using the viewfile macro.
- You may see that this affects certain fonts, eg. MS-Mincho, Arial, etc.
Cause
The JVM relies on the available fonts installed in your operating system. If you don't have the required fonts, you will see your utf-8 characters rendered as boxes in viewfile macro. For example, if you have Arial font and not MS-Mincho, you may discover the UTF-8 characters can be rendered when using Arial as a font and not the other.
Resolution
- Make sure that your operating system has the required fonts eg.
ARIALUNI.ttfto render the UTF-8 characters. - If using Windows, you may need to purchase the font from a third party and install the required font in
C:\Windows\Fonts.
