return utf-8 character inside ruby method

Question

I want to return the utf-8 tick character ✔ ✔ in my ruby method.

I reason I am doing it in my method is because I need that character in an excel column generated by rails axlsx.

I know we can use the content_tag to return html block tag, but not sure how I can use it to return the utf-8 character. If there is an alternative can someone please suggest me one.

You could just return the "✔" String, if you have utf-8 encoded source file I'm fairly certain that works. Alternatively, you can use "\u{codepoint}" to return a unicode character of a specific codepoint. That codepoint in your case is 2714 (hex), so you can do:

def checkmark
  "\u{2714}"
end

I kind of like this approach better. – newbie Mar 11 '14 at 16:53

one question why the number `2714` inside `{}` ? – Arup Rakshit Mar 11 '14 at 17:22
@ArupRakshit Good question, I thought it was meant to be like this and worked when tested. Turns out it does not need to be :) – Daniël Knippers Mar 11 '14 at 19:25

That's easy:

def my_method
  '✔'
end

There is no `&` in my answer, what are you talking about? – Jörg W Mittag Mar 11 '14 at 16:49
