I am Facing these errors, don't know why when I run pod update it gives me this error. Any solution??

This issues appeared in Cocoapods 1.11.0 and as many already noticed rolling back to 1.10.2 fixes the issue. But the original issue comes from wrong locale set in the terminal. It has to be a UTF-8-based locale.

You can run 'locale' in the terminal to check current locale settings. It should be something like this:

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL=

If you have ascii-based locales set or "C" (which is also an ascii locale) then run

export LC_ALL=en_US.UTF-8

If you prefer some other locale (not en_US) then run locale -a to see the list of available options and pick UTF-8 locale you prefer.

Actually CocoaPods warns that UTF-8 locale is required:

WARNING: CocoaPods requires your terminal to be using UTF-8 encoding.
    Consider adding the following to ~/.profile:

    export LANG=en_US.UTF-8

But before 1.11.0 it was required only in case you use pods which contain non-ascii symbols in their names (Chinese for example) but starting 1.11.0 it become more strict. There is a discussion on Cocoapods GitHub about it: https://github.com/CocoaPods/CocoaPods/issues/10939

The answer of Vyacheslav Kormushkin worked for me.

Concretely, what I did was:

• open Terminal
• type open ~/.zshrc (or .profile if you don't use zsh)
• add export LC_ALL=en_US.UTF-8, and save the file
• go back to Terminal
• type source ~/.zshrc
• type locale

==> The locale will now be fixed

==> You can now safely run pod update or pod install
