Instance Method Details

#charset ⇒ Object

The charset of the response. HTML wants to know the encoding of the content you’re giving them, so we need to send that along.

def charset
  header_info = parsed_content_type_header
  header_info.charset || self.class.default_charset
end

#charset=(charset) ⇒ Object

Sets the HTTP character set. In case of nil parameter it sets the charset to default_charset.

response.charset = 'utf-16' # => 'utf-16'
response.charset = nil      # => 'utf-8'
