Delete non-UTF characters from a string in Ruby?

Question

How do I delete non-UTF8 characters from a ruby string? I have a string that has for example \"xC2\" in it. I want to remove that char from the string so that it becomes a valid

Answer 1

You could do it like this

# encoding: utf-8

class String
  def validate_encoding
    chars.select(&:valid_encoding?).join 
  end
end

puts "testing\xC2 a non UTF-8 string".validate_encoding
#=>testing a non UTF-8 string
