Why question marks when writing an image in JimpJS?

Question

Node.js

When saving an image, the Cyrillic text is converted to "question" marks, how can I fix this? https://github.com/oliver-moran/jimp

Jimp.read('./data/stats.jpg', (err, image) => {
        if (err) throw err;
        Jimp.loadFont(Jimp.FONT_SANS_64_WHITE).then(font => {
            image.print(
                font, 1, 1, {
                    text: 'Тест'
                }, 500, 500
            );
            image
                .quality(60)
                .write('./data/stats/test.jpg')
        });
    });

This image is saved:

Answer 1

The creation of the font https://github.com/libgdx/libgdx/wiki/Hiero helped. And its loading Jimp.loadFont('...')
