About Windows Phone 8 support

If there is no WP8 support, any tips to port it to WP8?

I believe you need to create a library (probably in cpp , maybe c# is also possible) and call text to bitmap rendering APIs that exist in WP8. After that you need to create a texture with it and inform unity-sysfont of that texture's pointer/id.

Take a look here first.

This is a quick google search, but I think you need something "close" to this.

You would have to create something very close to this (android source):

https://github.com/imkira/unity-sysfont/blob/master/android/src/com/github/imkira/unitysysfont/TextureUpdate.java
https://github.com/imkira/unity-sysfont/blob/master/android/src/com/github/imkira/unitysysfont/UnitySysFont.java

The first one should be very easy, the second one involves like I said above rendering text to a bitmap and creating an OpenGL ES texture with it.
