setting locale and language in terminal problem - encoding

Question

I use zsh for my terminal with iterm2 (macOS 14 Mojave). I get numerous numerous numerous issues with setting the locale and language. the most recent issue being that I can't use cocopods for my ionic application because gems can't be as root. This issue comes down because my terminal needs to have UTF-8 encoding, which it does. I have had this issue so so so much that I have put export LANG=en_US.UTF-8 in the .zshrc file, the .profile file and .bashrc file. I have ran the command $ source ~/.zshrc on ALL of the files mentioned above. I have closed terminal completely, and restarted my computer. No matter what happens and whenever I look inside the file ALL that information is there. the same issue happens whenever I try to open up neo vim I get the output:
Warning: Failed to set locale category LC_NUMERIC to en_ES.UTF-8.
Warning: Failed to set locale category LC_TIME to en_ES.UTF-8.
Warning: Failed to set locale category LC_COLLATE to en_ES.UTF-8.
Warning: Failed to set locale category LC_MONETARY to en_ES.UTF-8.
Warning: Failed to set locale category LC_MESSAGES to en_ES.UTF-8.
here is my .zshrc
export ZSH="/Users/me/.oh-my-zsh"
export LC_ALL=en_ES.UTF-8
export LC_NUMERIC=en_ES.UTF-8.
export LC_TIME=en_ES.UTF-8.
export LC_COLLATE=en_ES.UTF-8.
export LC_MONETARY=en_ES.UTF-8
export LC_MESSAGES=en_ES.UTF-8.
export LANG=en_US.UTF-8
ZSH_THEME="powerlevel9k/powerlevel9k"
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(dir rbenv vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status root_indicator background_jobs history time)
POWERLEVEL9K_PROMPT_ON_NEWLINE=true
POWERLEVEL9K_PROMPT_ADD_NEWLINE=true
POWERLEVEL9K_VCS_MODIFIED_BACKGROUND=’red’
POWERLEVEL9K_MULTILINE_FIRST_PROMPT_PREFIX="%f"
local user_symbol="$"
if [[ $(print -P "%#") =~ "#" ]]; then
user_symbol = "#"
fi
POWERLEVEL9K_MULTILINE_LAST_PROMPT_PREFIX="%{%B%F{black}%K{yellow}%} $user_symbol%{%b%f%k%F{yellow}%} %{%f%}"
plugins=(
git
zsh-autosuggestions
)
source $ZSH/oh-my-zsh.sh
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
echo -e "\033]6;1;bg;red;brightness;18\a"
echo -e "\033]6;1;bg;green;brightness;26\a"
echo -e "\033]6;1;bg;blue;brightness;33\a"
then this is what I get from nvim when running the :checkhealth

Answer 1

on my .zshrc file I added the following
export LC_ALL=en_US.UTF-8
export LC_CTYPE=en_US.UTF-8

Note that at the time when I found out the answer I wasn't allowed to post an answer because there wasn't enough time that passed.
As for the asnwer why this works. I have no idea, I am not too familiar with this type of Linux/shell permissions, encoding, etc.
