Welcome to linux. Don't let this problem worry you, it's been an issue before and is being worked on.

Just a few cool things that you can do on the command line (terminal) to get more comfortable are:

whois google.com - the "whois" command, followed by a website domain name, will show ownership information etc. about a website.

man nikto - the "man" command (short for manual) before a program name, like "nikto" will, will show you the manual and teach you about how to use that program.

man can also be used for command line commands; like "man ifconfig".

The Kali website also has some great information. Now, for your text problem:

Try opening a terminal (command line) and entering:

apt --reinstall install fonts-cantarell

Then restart.

Also, when updating, run:

apt-get update && apt-get upgrade && apt-get dist-upgrade

apt-get update by itself only downloads an updated package list (what has a new version ready for download).

Have fun.
