starship: Unable to see "🐪" using Konsole on Debian

Hi. I’ve been testing spaceship recently and I couldn’t help but notice how some symbols are not represented correctly… like when I enter certain folders (in this case a folder with perl script, but that as soon as I happen to see others, i show it to you) on the prompt I get a “rectangle”. The following is the code of the symbol in question:

00000000  f0 9f 90 aa 0a                                    |.....|
00000005

I installed all the “nerd fonts” fonts (more than 6gb of fonts!) in the system. In addition, the “awesome fonts” too, but nothing … that symbol (and others) are not displayed correctly.

My config:

Example problem (in this case, PERL directory):

My system is:

Debian 9 (amd64) DE KDE
