Dollar sign is not displayed correctly with decimal.ToString("C", CultureInfo.InvariantCulture);

I don't like asking such a small problem, but I found nothing and have no clue, why it's acting like this...

In one of my WebAPI (.NET Core) projects I have declared the following very simple method.

private static string GetDiffText(decimal diff)
{
    var abs = Math.Abs(diff);
    string diffText;

    var absoluteValue = abs.ToString("C", CultureInfo.InvariantCulture);
    if (diff >= 0)
    {
        diffText = $"+{absoluteValue}";
    }
    else
    {
        diffText = $"-{absoluteValue}";
    }
    return diffText;
}

The results of the ToString()-line should be: $23.59

But it actually looks like this:

Whats weird about it: When I use my default culture (which is €), the Euro-sign is correctly. So why does the dollar sign make such problems?

What do you expect the InvariantCulture's symbol to be? – Richard Schneider Jul 01 '18 at 09:06
@RichardSchneider I would expect it to display $23.59? Is that not what InvariantCuliture should do? – Jannik Jul 01 '18 at 09:09

Wrong. The invariant currency symbol is `¤`'. – Richard Schneider Jul 01 '18 at 09:12
Ohhh, wow, I didn't know that, thank you for the duplicate-link. – Jannik Jul 01 '18 at 09:12

Btw, you *can* use format specifiers within interpolated strings: `$"+{abs:C}"` although it'll use current culture, not invariant. You can use `FormattableString.Invariant($"+{abs:C}")` if you needed invariant culture – pinkfloydx33 Jul 01 '18 at 19:56
I didn't know that thank you :) I solved the issue by defining the culture I needed and using it inside string.Format :) – Jannik Jul 02 '18 at 10:09
