Monaco font in Konsole
Solution 1:
A workaround
Make a new or edit the current konsole profile. The konsole profile is saved to the ~/.kde/share/apps/konsole/.
Here, making a new profile: Test. Konsole > Settings > Configure profiles > New Profile. The ~/.kde/share/apps/konsole/Test.profile (font:Andale Mono):
[Appearance]
ColorScheme=Linux
Font=Andale Mono,9,-1,5,50,0,0,0,0,0
[General]
MenuIndex=2
Name=Test
Parent=FALLBACK/
RemoteTabTitleFormat=%h : %u
Editing the Test.profile, changing the font to the Monaco:
[Appearance]
Font=Monaco,9,-1,5,50,0,0,0,0,0
[General]
MenuIndex=2
Name=Test
Parent=FALLBACK/
RemoteTabTitleFormat=%h : %u
Closing all Konsoles, relaunching the konsole.
After this the Konsole text size for the Monaco font can be changed with the Text size slider.
