First of all, there were no images attached to your mail. Secondly,
you are barking up the wrong tree, sorry: FreeType is a very low-level
library, and all the possible causes you describe are not directly
related to FreeType at all. If your font works as expected with one
of our demo programs like `ftview` (of which I'm quite sure), then
FreeType's job is done.
I suggest that you contact a Kubuntu forum. If this doesn't help, try
to find help within the KDE community. As a last resort, contact the
terminal app and FontConfig maintainers.
