Ruby 3.2.0 / Rails 7.0.4 invalid byte sequence in UTF-8 (ArgumentError) about image_optim HOT 4 CLOSED

Upon closer inspection, i think this is due to missing binaries.

Thanks for your time

From the error looks like running pngout 2>&1 in your environment gives a string that can't be converted to UTF-8.
What does running `pngout 2>&1` output and what is the encoding of the string?
And environment questions:
Is it dependant on ruby version and presence of rails?
Is it plain irb, rails console or something else?
Something special about the environment?

This started happening after upgrading Ruby 3.1 to 3.2, and yes this is in the context of a Rails 7.0.4 app.

Is it plain irb, rails console or something else?

Rails console

Something special about the environment?

In the same console, as ImageOptim.new

Using Docker

Would you be able to create minimal reproducible example then?
