Description JonnyRobbie 2017-04-10 09:55:43 UTC
Tested on Arch Linux

$ uname -roms
Linux 4.10.6-1-ARCH x86_64 GNU/Linux
$ konsole -v
konsole 16.12.3
$ kf5-config -v    
Qt: 5.8.0
KDE Frameworks: 5.32.0
kf5-config: 1.0

1. Set Konsole font to any bitmap font. I've tried "GohuFont" from AUR or "Misc Foxed" from extra/xorg-font-misc. Both seem to have the same issue.
2. Display any unicode character: `echo "příliš žluťoučký kůň úpěl ďábelské ódy"`
Those characters above cp255 are not rendered with GohuFont even if GohuFont should contain those characters http://i.imgur.com/Ipkk4WT.png

Expected result: Well, fonts rendered correctly, like in st: http://i.imgur.com/E5rh7zP.png

Note: If I set to draw intense characters in bold, Konsole suddenly renders those characters in GohuFont, but in their regular variant: http://i.imgur.com/bRCiXoL.png

Note 2: The issue is not only in Konsole, but in Kate as well. (So I suspect it may be a Qt issue, but I'm not sure)

I now use 1.5 display scaling, so I hope this doesn't affect this, but it seems like it works fine now. The font does not get scaled, but it is expected from a bitmap font.
