manpage generator: encoding issue

[deining]

Using the new man page generation feature, I tried to generate a man page for the I18NDemo given in the examples section of the repo.

When invoking ascciidoctor on the produced .adoc file, I'm getting:

Failed to load AsciiDoc document - invalid byte sequence in UTF-8

I can easily cure this by adding the encoding attribute to the produced .adoc file:

// tag::picocli-generated-full-manpage[]
// tag::picocli-generated-man-section-header[]
:doctype: manpage
:encoding: ISO-8859-1

IMHO, encoding is something that should be considered by the man page generator.
AFAIK, since Java 9, to can use UTF-8 encoding for your resource bundles, so simply adding the encoding attribute to the generated file seems to be no valid option for me. Maybe we can overcome this by adding an additional encoding option to the gen-manpage command?

I see, yes that makes sense.
The default value would be the platform encoding, I guess.
Sounds like a good idea.
Will you be able to provide a pull request for this?
