Create QByteArray JSON with special characters (é, ...) as unicode (\uxxxx)

[Mixlu]

I would like to create a simple JSON structure like follow :

{ "é" : 1 }

And to finally get it as a valid JSON QByteArray.

Here is my code in order to achieve this :

QJsonObject data;
data.insert("é", 1);
QJsonDocument jsonDoc(data);
QByteArray bjsonData = jsonDoc.toJson();

But here the "é" is stored as "\xC3\xA9", it is the UTF-8 representation of the character but I would like to get "\u00e9" instead (the unicode code point) as specified by the JSON RFC.

Is there a way to get escaped Unicode value instead of escaped utf-8 value ?

It is not escaped.
It is just the QDebug output of unprintable char.
If you convert the QByteArray to a QString with QString::fromUtf8(), it is still a "é".

@Bonnie said in Create QByteArray JSON with special characters (é, ...) as unicode (\uxxxx):

unprintable

Ahh fine, thanks for the reply.

And so is there a way to get the Unicode escaped format ?

@Mixlu
What do you mean by "Unicode escaped format"?
Normal characters won't be escaped, even a character like é also doesn't need to be escaped.
If you use some special characters like \0, then it will be escaped to \u0000
