Decimal separator: point or comma

Hello Adrian,

first off, awesome work! I really like your plugin, I am using it to add an optional donation in the checkout process.

I have setup fixed values, and when you click on “custom value”, you can put in decimal values only if you use a point as decimal separator. Here in Germany, we use a comma instead, and I expect my customers to do exactly that.

However, the comma is then simply removed/ignored, and the input value is for example 350 € instead of 3.50 €.

Could you modify your plugin to handle this correctly? I am thinking of these possible solutions:
– accepting point or comma as decimal separator
– querying the default decimal separator from WooCommerce (if possible)
– including an option in your plugin settings

Thanks!

Florian
