This question already has an answer here:
I have been trying to style some OSMM data using their supplied QML files which include a font with some of their symbology in. I've added the font to my system (ubuntu 14.04 LTS) and when viewed in FontMatrix and other system font tools it looks fine:
But when I come to use it in QGIS the font has no glyphs visible and I end up with ugly rectangles instead of my symbols.
Is there some trick to get QGIS to recognise this font?
