An error occurred while installing byebug (2.7.0), and Bundler cannot continue

I am getting following error when i am doing bundle install or bundle udpate

An error occurred while installing byebug (2.7.0), and Bundler cannot
continue.
Make sure that `gem install byebug -v '2.7.0'` succeeds before bundling.

If i do sudo gem install byebug -v '2.7.0' i get

Building native extensions.  This could take a while...
Successfully installed byebug-2.7.0
Parsing documentation for byebug-2.7.0
unable to convert "\xCA" from ASCII-8BIT to UTF-8 for lib/byebug/byebug.bundle, skipping
1 gem installed

and then if i do bundle install or bundle udpate i get same error.

I tried removing byebug from gem file but then if i try to go to console, i get

bin/console:6:in `require': cannot load such file -- byebug (LoadError)
    from bin/console:6:in `<main>'
