There is no real problem in this very case: the data is uploaded correctly, it is just S3 does not serve the encoding (it simply does not know it) and google chrome does not have enough context to guess it right.

blocks|key|640936|text|正如zerkms所述，来自S3的文件中的字节与节点服务器的文件相同。问题是S3的web客户端没有告诉浏览器在从S3打开JSON文件时使用uft-8。因此，Chrome以屏幕截图显示的方式显示字节。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|640937|这一切都是真实和好的，但是，它无助于解决最初想要的结果，即从S3+web客户端看到表情符号。|640938|修复方法是将charset=utf-8+添加到s3上传选项中，如：|offset|length|style|BOLD|CODE|640939|s3.upload({

++++Body:+JSON.stringify(thing),
++++ContentType:+'application/json;charset=utf-8'
})|code-block|syntax|javascript|640940|此外，设置ContentEncoding:+'utf-8'不会导致所需的行为，这是毫无价值的。|640941|entityMap^0|0|0|6|D|K|D|6|D|0|0|0|1B|5|O|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|V|8|@$F|W|G|X|H|I]|$F|Y|G|Z|H|I]|$F|10|G|11|H|J]]|9|@]|A|$]]|$1|K|3|L|5|M|7|12|8|@]|9|@]|A|$N|O]]|$1|P|3|Q|5|6|7|13|8|@$F|14|G|15|H|I]|$F|16|G|17|H|J]]|9|@]|A|$]]|$1|R|3|-4|5|6|7|18|8|@]|9|@]|A|$]]]|S|$]]

As zerkms stated, the bytes in the file coming from S3 were the same as the node server's file. The issue was that S3's web client did not tell the browser to use uft-8 when opening the JSON file from S3. As a result, Chrome showed the bytes in the way the screenshot displays.

This is all true and good, however, it doesn't help solve the original desired result, which is to see the emojis from the S3 web client.

The fix was to add <code>charset=utf-8</code> to the s3.upload options, like so: 

<pre><code>s3.upload({
 Bucket: myBucket,
 Key: 'myPath/' + thing.id + '.json',
 Body: JSON.stringify(thing),
 ContentType: 'application/json;charset=utf-8'
})
</code></pre>

Additionally, it is worth nothing that setting <code>ContentEncoding: 'utf-8'</code> did not result in the desired behavior.

Incase anyone needs to do this via the AWS cli:

<code>aws s3 sync ./build s3://your-s3-bucket --exclude "*.js"</code>

uploads all build folder files regularly, except js which contains utf-8 emoji characters

then

<code>aws s3 sync --content-type "text/html; charset=utf-8" ./build s3://your-s3-bucket --exclude "*" --include "*.js"</code>

uploads js files that contain utf-8 emoji characters with utf-8 encoding

*note: option order is very important in aws-cli

I am uploading a JSON string from my nodejs server, into S3, via the <a href="http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#upload-property" rel="nofollow noreferrer"><code>s3.upload</code></a> method. 

<pre><code>var s3 = new AWS.S3();

s3.upload({
 Bucket: myBucket,
 Key: 'myPath/' + thing.id + '.json',
 Body: JSON.stringify(thing),
 ContentType: 'application/json'
})
</code></pre>

If in the above snippet, the <code>thing</code> object has a String property containing emojis, how would I modify this operation in order to preserve the emoji characters.

At my node server, I can see that the emoji is being stored in the DB and served correctly. It is only after upload do the characters lose their integrity. I think there's some character encoding trick that I can apply to the JSON.stringify result, but I don't yet know the details. Asking for help here.

JSON I get at node server:

<a href="https://i.stack.imgur.com/NxX0y.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NxX0y.png" alt="enter image description here"></a>

JSON I see at S3:
