"init_converters" method receives an extra parameter in Ruby 2.5.3

[j3pic]

Expected Behaviour

What should happen?

When Csvlint is loaded into Ruby 2.5.3, it should validate valid CSV files, just like
it does in older versions of Ruby.

Current Behaviour (for problems)

What currently happens that isn't expected behaviour?

Csvlint reports :invalid_encoding for all lines. It turns out this is because it is assumed that the only reason an ArgumentError will be thrown is if there's invalid encoding.

When I commented out the rescue statements, I got this backtrace:

    Exception: ArgumentError: wrong number of arguments (given 3, expected 1..2)

Here's how init_converters is being called by Ruby:

    init_converters(converters, :@converters, :convert)
    init_converters(header_converters, :@header_converters, :header_convert)

Csvlint's implementation of init_converters only accepts 2 parameters:

2. Evaluate this:

File.open "/some/file.csv" do |f|
  new_linter = Csvlint::Validator.new(f,
                                      {"header"=>true, "skipInitialSpace"=>true, "delimiter"=>",", 
                                       "quoteChar"=>"\""}, nil, {:batch_size=>1000,
                                                                 :allow_quoted_linebreaks=>false})
end
