Swift，php和unicode字符

Question

I am using a url request to receive data from MySQL. The data is received in a JSON format. This data also includes unicode characters (for example greek letters).

Then, in Swift, I am using JSONSerialization like this:

if let json = try JSONSerialization.jsonObject(with: data!, options: []) as? [String: Any] {

The keys of json are number indices. Then I take a nested dictionary like this:

let dictionary = json[key] as? [String: Any]

Then I assign:

var content = dictionary!["content"] as! String

This content has unicode characters inside it.

Unicode characters appear like this (if I print dictionary): \U03b1 (for the greek letter Alpha).

The problem is that Swift cannot read those characters because Swift expects unicode characters to be like this: \u{03b1}.

The value of content is an empty string: ""

How can I solve this? Either have PHP send those characters in the way the Swift "understands" them, or having Swift decoding the incoming data in the proper way.

Any ideas?

Thanks!

I do have the same kind of issue for multiple currency symbols. API team is passing now '\u0024' and it has resolved issue in Swift. May be you can try same from API side.
