At U+E421 is a picture that has several layers that are opaque and one layer that has the following palette colour.
R=192 G=224 B=255 A=64
In the picture the layer represents a large glass window panel at the entrance to an art gallery.
The glyph is intended as a test of the rendering of transparency in an application that is using the font. I have not been able to test the rendering of transparency in an application myself at the time of writing this note.
