I have an issue with changing the font of a text zone in the QGIS composer.
I have downloaded Roboto font and want to use it in my composer instead of Arial black. After installation I quitted QGIS and relaunched it. The font is available in the font list yet when I apply it, it doesn't seems to be changing.
I'm running with QGIS 2.18.20 on a MacBook Pro Machine.
How can I handle this?
