Re: [Interest] QJSEngine won't evaluate octal literal

[Fabrice Mousset | GEOCEPT GmbH]

I don't know why (perhaps the "strict mode" is always active with Qt?), but you 
to use 0o11 to force octal encoding to avoid confusion with binary encoding 
(0b11).

QJSEngine eng;
auto jsv = eng.evaluate("(function(){return 0o11;})()");
qDebug() << jsv.isError() << jsv.toString() << jsv.toVariant();

[Interest] QJSEngine won't evaluate octal literal

[Hamish Moffatt via Interest]

I have the following test code to evaluate an octal literal which I'm 
running on Qt 5.12 and 5.15;


            QJSEngine eng;
            auto jsv = eng.evaluate("(function(){return 011;})()");
            qDebug() << jsv.isError() << jsv.toString() << jsv.toVariant();

This outputs:

true "SyntaxError: Expected token `;'" QVariant(QVariantMap, QMap())


It works if I use hex literals, and the octal code works in node.js. Why 
doesn't it work in QJSEngine?
