Per https://fedoraproject.org/wiki/Changes/NewDefaultConsoleFont Fedora's 'default' console font is supposed to be eurlatgr as of Fedora 22, but anaconda does not use it. (Prior to F22 the default was supposed to be 'latarcyrheb-sun16'; F21 anaconda does not use that either). It seems that systemd loads the font specified in /etc/vconsole.conf if it exists, otherwise it does not load a font at all, meaning the font used will be the firmware's font. In the anaconda environment there is no /etc/vconsole.conf . bcl posted a patch - https://paste.fedoraproject.org/251555/14387227/ - which should add a vconsole.conf and, if our theory is correct, solve this bug. I'm going to test it. The impact of this is fairly low for most cases, except it caused me some headaches with openQA...
What about bug 1209460?

davidshea: the firmware font is unlikely to have any better glyph coverage than eurlatgr, so we're not likely to make anything worse by loading it. We could try and get cute and load the appropriate font according to langtable after the user goes through the Welcome screen, I guess, but that seems like extra work and I'm not sure how critical it is; I don't think there's much need for people to use non-ASCII characters at the system console during install. I would never have noticed this if not for the openQA match problems.
