Describe the issue you encountered

Hello; I have a Ubuntu 16.04 guest machine on vmware (my host is Windows 11). I am using Terminator but I have also tested on xfce-terminal I have installed needed nerd, patched and powerline fonts! I am using Hack Nerd Font Mono (I have also tried on Fira Nerde and Meslo Nerd fonts)

I have installed gef stated in the README manually. When I run a binary using gef I have this weird issue:

For better Understanding I have included screenshots. (Those squares are actually '\x0001' and '\x0002' bytes)

MORE on that Xubuntu 16 comes with GDB7.11 and python2. So I also have tried gef legacy but the issue is still the same!

Do you read the docs and look at previously closed issues/PRs for similar cases?

Describe your issue. Without a proper reproduction step-by-step, your issue will be ignored.

1. Bring up an Xubuntu 16.04 image(I am using it on vmware)
2. install gef manually
3. run gdb or gdb <binary-name>

Minimalist test case

No response

Additional context= Screenshots

BTW; as you can see in the last screenshot; I have given the command disas main and there is no problem in the colored output :/

This seems to be coming from your terminal, not GEF. I'd recommand you try another terminal and make sure you're using UTF-8 charset.

True! It is not about gef; it is about the version of terminator. On Ubuntu 16.04 it is 0.91. This version does not support lots of things. I have used latest terminator version (v 2.1.4) without problem.

Thanks for your reply
