Rails: How can I test for the presence of ¡ in mailer text?

Question

I'm trying to rewrite an rspec mailer test and I cannot figure out how to account for the special character ¡ in this text:

<p>
  You have been added to the <%= @user.organization.name %> organization in &#161;Generic!
</p>

Here's a snippet of the failing test:

 it 'renders the body' do
      puts @user.email
      body = mail.body.encoded
      #The following line is obviously incorrect, just an idea of what I'm trying to achieve
      body.should match "You have been added to the #{@user.organization.name} in ¡Generic!"
 end

I'm still super new to everything above basic rspec, and could really use some guidance on how to test for the presence of the inverted exclamation point 😅.

Thanks!!!

UPDATE

I've was able to get the correct text displayed in the console error, but it still doesn't match. Here's how I did it:

it 'renders the body' do
  
  body = mail.body.encoded
  body.should match 'Hello [email protected],'
  body.should match "You have been added to the #{@user.organization.name} organization in \u{00A1}Generic!"

and here's the new error:

Answer 1

Well if you indeed only want to check if the ¡ is in the body, you could write it (the last line) up like this:

expect(body.match?(/¡/)).to eq true

So just a regexp that matches the special character you mentioned, and returns true if it is found, then use that as the condition for the test matcher.
