There are multiple possible causes for this problem.

1) Your text file is not encoded in UTF-8.

You need to check that your editor/IDE (i.e. NetBeans) saves the file in
UTF-8.

2) Your editor’s output windows is not set up for UTF-8 output.

You need to reconfigure your IDE to expect your program’s output in
UTF-8.

3) You are using the Windows commandline (DOS box).

You need to change the Windows commandline’s configuration to UTF-8
instead of Windows-1252.

Background:

Windows systems in western countries by default work with the
Windows-1252 encoding, which is a variant of ISO-8859-1. Both of these
encodings are incompatible with Ruby’s default encoding, which is
UTF-8. When you try to display a UTF-8-encoded text in a textbox that
expects its input to be Windows-1252, you’ll receive the results you
got. The proper solution is to change the output program to expect
UTF-8, which is the correct modern-day encoding to use rather than the
archaic Windows-* encodings from the 90ies, which is what I have
recommended above. It is AFAIK also possible to have Ruby automatically
transcode everything to Windows-1252, but I don’t know how. Also, UTF-8
can contain many more characters then Windows-1252, and it is likely
that sooner or later you run into problems with characters that can’t be
represented in Windows-1252. Hence, the better solution is to change
your tooling to expect UTF-8.

Valete,
Quintus.
