Ruby on Rails - £ sign troubles

问题:

I have <%= f.label :cost, "Cost (£/m)" %> in a form. When the form is rendered the "£" sign comes out as �. I am using utf-8 encoding. Why is this happening?

回答1:

Suggestion from my experience) :

1. verify that your file erb is saved in utf-8
2. I recomend you to use number_to_currency method

回答2:

Are you outputting HTML? If so you need to escape the character <%= f.label :cost, "Cost (&pound;/m)" %>

回答3:

Either send your page with UFT-8 encoding, or send the pound sign as £ (or £ if you're sending XML rather than HTML).
