Normally I am working on a Linux machine using vim and tmux with the powerline statusline plugin. However, sometimes I am forced to work on a windows machine. Whenever possible I open a ssh connection with PuTTY to my Linux machine to work remote on it.
It turned out that the fonts of powerline were not displayed correctly.
To fix this, I did the following modifications:
DejaVuSansMonoas my font since I like it most.
appearanceselect the patched font
If everything worked well, powerline should be displayed correctly in PuTTY.
