Changing non-standard ASCII character casing (UTF-8)

Ruby JRuby

I’m looking for some information on changing the casing of non-standard
ASCII
UTF-8 characters in JRuby.

In MRI, it appears the unicode gem is the recommended approach for this:

Is there a recommended approach in JRuby?

Fortunately I’ve discovered a way to do this. Unfortunately it requires
explicit use of Java.

s = “Café”
=> “Café”
s.upcase
=> “CAFé”
s.to_java_string.to_upper_case
=> “CAFé”
java.lang.String.new(s).to_upper_case
=> “CAFÉ”

It’s intriguing that converting from a Ruby to a Java String does not
behave
the same way as creating a Java String.
Furthermore;

s.to_java_string.to_s
=> “Café”

Suggests that the encoding of the converted String is incorrect.
