+### Ruby 3.4
+
+nkf/kconv has been part of Ruby since long ago.
+Eventually it became a standard gem, but was changed to a bundled gem in Ruby 3.4.
+In general, kconv and iconv have been superseded since Ruby 1.9 by the built-in
+encoding support provided by String#encode, String#force_encoding, and similar methods.
+But this gem has not yet been updated to remove its dependency on nkf/kconv.
+
+As a result of all this you should add `nkf` to your Gemfile if you are using Ruby 3.4 or later.
+
+```ruby
+gem "nkf", "~> 0.1"
