posting Chinese characters or special characters to AEM using cURL

[何塞]

Hi guys,

Today I just want to share with you a way to post Chinese characters (or special characters) to AEM using cURL. This all started with me trying to restart an asset workflow using cURL. Here you can find instructions on how to do so, the example relevant to this post from that article is:

curl -u admin:admin -d "model=/etc/workflow/models/request_for_activation/jcr:content/model&payload=/content/geometrixx/en/company&payloadType=JCR_PATH&workflowTitle=myWorkflowTitle" http://localhost:4502/etc/workflow/instances

If your "payload" request parameter contains Chinese characters, after you execute this command you will notice the Chinese name on AEM has been corrupted. So to get started I modified the above command as follows:

curl -v -u admin:admin -F model="/etc/workflow/models/dam/update_asset/jcr:content/model" -F payloadType="JCR_PATH" -F payload="/content/dam/何塞.png" http://localhost:4502/etc/workflow/instances

After executing it my payload would look like this on AEM: /content/dam/何塞.png

If you add _charset_="utf-8" to your parameters in the cURL command the Chinese name would be posted correctly. So the final version of the command looks like this:

curl -v -u admin:admin -F model="/etc/workflow/models/dam/update_asset/jcr:content/model" -F payloadType="JCR_PATH" -F payload="/content/dam/何塞.png" -F _charset_="utf-8" http://localhost:4502/etc/workflow/instances

Now my payload name on AEM displays and executes correctly as: /content/dam/何塞.png

During the time of my research I came across this article where you will find another workaround to post special characters to AEM. In this article I found this command:

curl -u admin:admin -X POST --data "test=€ , Š , Œ , ™ , š , œ , ž" http://localhost:4502/content/mynodetest

Which is incapable of posting those special characters to AEM (they get corrupted once they are in AEM). I modified it as follows:

curl -v -u admin:admin -F test="€ , Š , Œ , ™ , š , œ , ž" -F _charset_="utf-8" http://localhost:4502/content/mynodetest

And voila! problem solved, special characters posted correctly to AEM 

Hope this helps anyone out there looking for a simple solution to this, including myself in case I forget it in the future
