var sg = sendgrid.SendGrid("xxxxxxxxxxxxxxxxxxx");
var requestPost = sendgrid.emptyRequest;
requestPost.method = 'POST';

@eaparango this is a library problem. I was able to successfully send your email through these examples: https://sendgrid.com/docs/Classroom/Send/v3_Mail_Send/curl_examples.html

So I'm filing this one as a bug and we will figure out a fix.

OK, I think I've found the fix:
https://github.com/sendgrid/nodejs-http-client/blob/master/lib/client.js#L76
needs to be Buffer.byteLength(body)

[thinkingserious]

The fix is in place in version 3.0.5. I've tested against your code above and it now works.

The issue was in the way I was calculating the content-type length. I did not account for the varying byte lengths of unicode characters.
