I don't understand this. List store is not a list it is a tree model where
all rows are siblings.

Presented by what? By a cell renderer? Which renderer? There are many cell
renderers. If you want to render characters as texts you should use a text
renderer and GType_String. I have no idea how text renderer is supposed to
render GType_Char, probably as a number.
