how to handle encoded cyrillic data in json using Qt?

Question

I have a JSON but all cyrillic characters are encoded like this: \u0418\u0437\u0431\u0435. How can I read this into QString?

Answer 1

That's JSON's Unicode escape sequence. You should use a JSON parser for this. There are some other gotchas in JSON parsing.

If you are using Qt 5, it comes with one: http://qt-project.org/doc/qt-5.0/qjsondocument.html

If you are not, then get a 3rd party one like jsoncpp. It's rather lightweight and not to difficult to convert between its data and Qt's.

Answer 2

That's should be an UTF8 or UTF16 encoding. Use this:

result = QString::fromUtf8(yourString.c_str(), yourString.size());

or

result = QString::fromUtf16(yourString.c_str(), yourString.size());

where yourString is std::string type
