Encoding iso-8859-1 isn't working on rails 5

Basically project is upgraded from ruby 1.8 to ruby 2.5.

ISO-8859-1 encoding is declared on pages which works fine in previous ruby and rails version.

Also method is written in application controller.

  before_action :set_charset

  def set_charset
    response.headers["Content-Type"] = "text/html; charset=ISO-8859-1"
  end

application layout is declared like following.

  <meta http-equiv="content-type" content="text/html; charset=iso-8859-1">

but in ruby 2.5 at javascript_tag it gives following error.

<%= javascript_include_tag "application" %>

Encoding::InvalidByteSequenceError
"\xA3" on UTF-8

Tried following options at rails level but it won't work.

application.rb

   config.encoding = "ISO-8859-1"
   config.force_encoding = "UTF-8"
Solution

  • Removed all old js files from application. It started running.
