No, you have a problem with non-ASCII characters. ASCII is US-ASCII,
a-z, numerics and a small set of punctuation and special characters.

.... so, two non-ASCII characters.

Appears that you have some partially utf-8 -based environment.
That is, your environment states that you're using utf-8 as your
character encoding, and Java outputs sequences that would, in
true utf-8 environment provide the letter glyphs you were expecting.
Instead, your terminal emulator chooses to display the output in
some other encoding, perhaps iso-8859-1.
It used to be possible to force the encoding used by applications
with a system property named file.encoding, but at least the
tests I ran just now seem to indicate that the system property
is overridden by the locale environment variables.
You'll need to tell (by using LC_CTYPE environment variable)
to your Java VM which character encoding is used by your terminal
emulator. If it's iso-8859-1, you could use something like
LC_CTYPE=es_ES.iso88591 java Hola
to run your program on the command line.
And yes, character set issues (when you're working with anything
but US-ASCII) are a pain. And have been for more than two decades
already.
