Java callout | message content with non-ASCII characters

[tchelets]

Hi,
I have non-ASCII chars in the body request [Hebrew chars] like: {"address": "תמוז"}
Using the following Java code I can see: {"address": "????"}

package com.apigee.flow.message;
message.getContent()

But in the Debug tracing. I can see the correct chars in the Body.
Can you please advise? how to handle the content to support non-ASCII characters?
