This is a Squeezebox Applet, which will only work on the following SqueezeOS-based Squeezeboxes:
- Squeezebox Radio
- Squeezebox Touch
- Squeezebox Controller
The default FreeSans Font in the stock firmware for these squeezeboxes does not provide Unicode support.
The applet replaces the default FreeSans Font with a merged FreeSans + DroidSansFallback font to provide a fuller character set, including Chinese/Japanese/Korean characters.
