As you see in this image below, when I put the theme powerlever9k in zsh with oh-my-zsh the terminal is put in English and the accents do not catch them, any ideas?
SO: Arch linux, gnome-terminal and Tilix (terminix)
PS: only happens to me with this subject , the others themes of oh-my-zsh does not happen.

Thanks for the report @D4v2z . Interesting.
The only place we set locales is in functions/icons.zsh, because if the user did not set a locale, the icons would break with a nasty error message ("character out or range").
Have you set a locale?
@dritter Thanks for replying, my set in locale with powerlevel and Zsh

Theme "Agnoster" (for example) and Zsh

Theme powerlever9k and Zsh

Theme "Agnoster" (for example) and Zsh

Hope this can help you!
Could you install the locale for en_US.utf8 and see if that helps?
Background is that we had to pick a default locale for the utf8 code points in functions/icons.zsh to avoid further errors. For lowest impact, we chose en_US, as this is the most widespread locale around.
Good afternoon, he got to know that it is, in /etc/locale.gen I have enabled the "en_US.UTF-8" apart from the three of my language and it works, thanks for the help.
Awesome! Thanks for the report. I added it to the troubleshooting wiki page. And sorry for the inconvenience.
One thing, when you put '/etc/locale.gen' and to enable "LANG=en_US.UTF-8" you have to generate locale with 'sudo locale-gen' or like root 'locale-gen', otherwise it will not work.
It is for Arch:

That is an addition to the troubleshooting paragraph I wrote, right? Yeah, I had thought about adding some words on how to regenerate the locale. At last I skipped it, because it differs on the various OSes...
Btw. Your profile pic is perfect for this theme! :)
Thanks for that extra bit in the troubleshooting guide, @dritter, and I'm glad you're up and running, @D4v2z!
