force_encoding() should be replace with b() for ruby 3.4 or later

[bsdmad]

Problem

In lib/net/ber/core_ext/true_class.rb, force_encoding() is used.

ruby-net-ldap/lib/net/ber/core_ext/true_class.rb

Line 9 in de197ea

"\001\001\xFF".force_encoding("ASCII-8BIT")

Therefore it causes a warning like this on ruby 3.4 or later:

/usr/local/bundle/gems/net-ldap-0.20.0/lib/net/ber/core_ext/true_class.rb:9: warning: literal string will be frozen in the future (run with --debug-frozen-string-literal for more information)

Solution

I can surpress this warning with b() instead of force_encoding().

  def to_ber
    # http://tools.ietf.org/html/rfc4511#section-5.1
    "\001\001\xFF".b
  end
