Support different encoding in smallrye-open-api-maven-plugin

[ColdanR]

Hello,
I'm currently setting up an automated documentation for OpenAPI, but on Windows 10 the plugin exports the schema files with a different encoding than UTF8. (System Default)

Looking up the code the generated documentation will be transformed to an byte array without usage of encoding.

smallrye-open-api/tools/maven-plugin/src/main/java/io/smallrye/openapi/mavenplugin/GenerateSchemaMojo.java

Lines 431 to 433 in 0af0bec

	writeSchemaFile(directory, "yaml", yaml.getBytes());
	writeSchemaFile(directory, "json", json.getBytes());

So please allow to configure encoding or use utf-8 encoding as default.

Charset charset = StandardCharsets.UTF_8;
if (charsetParameter != null) {
try {
    charset = Charset.forName(charsetParameter);
} catch (IllegalArgumentException e) {
    throw new MojoExecutionException("Cannot find charset for " + charsetParameter);
}
}

writeSchemaFile(directory, "yaml", yaml.getBytes(charset));
writeSchemaFile(directory, "json", json.getBytes(charset));

Thanks,
Bernd Schmidt

Hi Bernd, thanks for the issue. Are you not keen to do a PR to fix this ?

Hi Phillip,
currently I don't have the time to do so. I also didn't find any information about contributing. Would be nice, if you can add a code of conduct and contribution.md file für information.
I will try to find some time next week.
