Here are some previous issues about your problem:

#313
#510
#543

So try fixing locale/make sure you're not calling it somewhere you shouldn't.

How do I fix it? When I run locale, it prints LANG=en_US.UTF8 LANGUAGE=en.UTF-8 LC_CTYPE=en_US.UTF-8 LC_NUMERIC="en_US.UTF8" LC_TIME="en_US.UTF8" LC_COLLATE="en_US.UTF8" LC_MONETARY="en_US.UTF8" LC_MESSAGES="en_US.UTF8" LC_PAPER="en_US.UTF8" LC_NAME="en_US.UTF8" LC_ADDRESS="en_US.UTF8" LC_TELEPHONE="en_US.UTF8" LC_MEASUREMENT="en_US.UTF8" LC_IDENTIFICATION="en_US.UTF8" LC_ALL=

It's possible your $LANG is malformed. I believe it is supposed to be LANG="en_US.UTF-8" - note the hyphen between UTF and 8. Try this at the top of your zshrc: export LANG=en_US.UTF-8

Sadly, that did not fix it. Here is my zshrc file: https://pastebin.com/VKJLPxkq

Okay so exactly like #543 - you have print_icon in your .zshrc, which loads before functions/icons.zsh, if I understand #543 correctly

How do I fix this? Thanks

@Apple61752 - Check out the link that @iScrE4m posted. There is a comment that describes how to fix it: #543 (comment)

You are making calls to print_icon before you have sourced Oh My Zsh. You need to run OMZ before you can reference print_icon in your zshrc

Hey @Apple61752 - We haven't heard back from you, so I'm going to go ahead and close this. If you are still having issues, feel free to re-open!

what is OMZ @bhilburn

Hi! This is a wonderful theme. Great work. I didn't have any issue using the theme but I get this error when I activate a python virtual environment using pipenv shell.

@mrdionjr On which branch/version of P9K are you? And can you show us your configuration?

I guess the latest version! I've just followed the instructions on the README. I use Oh My Zsh. I left most of the default settings. Here is my configuration

ZSH_THEME="powerlevel9k/powerlevel9k"
POWERLEVEL9K_MODE="awesome-patched"
POWERLEVEL9K_PROMPT_ON_NEWLINE=true
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(os_icon user dir dir_writable vcs)
POWERLEVEL9K_SHORTEN_DIR_LENGTH=2

I just noticed that it happens everytime I enter in a subshell. I tried to record the terminal session using termtosvg it I got the same error.

@mrdionjr Thanks for the Screenshot. Your problem is already adressed in #587 and will be fixed soon. For now you can set a valid utf-8 locale as LC_CTYPE.

It's already set. Here is the output of locale:

locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE=en_GB.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE=en_GB.UTF-8
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I've solved the issue by exporting LANG and LC_ALL:

export LANG=en_GB.UTF-8
export LC_ALL=""

I think it was due to LANG being overwritten somewhere. Thanks for your support.
