How can I use the pound sterling pound symbol in Ruby on Rail for the currency method?

Question

I am new to Ruby and Ruby on Rails.

Following the Ruby tutorial to create a small product search application, the author used the currency method number from Ruby on Rails. The problem is that the default device is $ , but I would like to change it to £ .

When I did this, he gave me the following error after I tried to run the code.

 number_helper.rb:7 invalid multibyte char (US-ASCII) (SyntaxError) 

Answer 1

Put the following on the first line of your file, where you have £ .

 #coding: utf-8 

By default, ruby ​​can read single-byte characters that are US-ASCII characters . The £ character does not fit into the US-ASCII code, and the magic comment above allows the ruby ​​to read the file as UTF-8 code, which becomes standard and is capable of handling multi-byte characters, including £ (Added after the Tin Man sentence).

Edit With Ruby 2.0, which will be published this month, the default encoding will be UTF-8, so you no longer need to do this.
