unknown operator error printed when opening a CJK font

[bitinn]

The font is https://github.com/adobe-fonts/source-han-sans

The code I use: https://github.com/bitinn/character-map

opentype.load(opts.f, function(err, font) {
    if (err) {
        console.log(err);
        return;
    }

    if (!font.glyphs || font.glyphs.length === 0) {
        console.log('no glyphs found in this font');
        return;
    }

    var table = '';
    font.glyphs.forEach(function(glyph) {
        if (!glyph.unicode) {
            return;
        }

        table += String.fromCharCode(glyph.unicode);
    });

    console.log(table);
});

The errors I see:

Glyph 123: unknown operator 9
Glyph 123: unknown operator 9
Glyph 162: unknown operator 0
Glyph 162: unknown operator 0
Glyph 162: unknown operator 0
Glyph 162: unknown operator 0
...

My guess is they are no big deal (I do get the correct characters at the end), but how can I suppress it?

I just tried several fonts of that font family with the latest master, using this adapted code:

var table = '';
Array.from(Object.values(font.glyphs.glyphs)).forEach(function(glyph) {
    if (!glyph.unicode) {
        return;
    }

    table += String.fromCharCode(glyph.unicode);
});

console.log(table);

It seems like this issue has been remedied over the years, so I'm closing this old issue. Please reopen or create a new one in case there is still anything wrong.
