Reading UTF-8 with BOM in ruby 2.5.0

Question

Is there a way to read files encoded in UTF-8 with BOM (Byte order marks) on Ruby v2.5.0?

On Ruby 2.3.1 this used to work:

 csv = CSV.open(file_path, encoding: 'bom|utf-8')

However, on 2.5.0 the following error ocurrs:

  ArgumentError:
    unknown encoding name - bom|utf-8

@knut - same result when using "BOM|utf-8", "BOM|utf8" , "BOM|UTF-8" or "BOM|UTF8" — romeu.hcf, Feb 19 '18 at 21:03

You can try this as well:

File.open(file_path, "r:bom|utf-8")

You can try this:

require 'file_with_bom'

File.open(file_path, "w:utf-8", :bom => true ) do |csv|

end

it works well
