How to allow separation by comma and period for input type of html5 number

Is there a way to resolve both a comma and a period as a separator using the html5 number input type? I found the decimal-separator property, but it seems to accept only one separator ...

Both types cannot be used in the html5 number input type. In fact, it can support decimal or floating numbers, as well as real numbers.

See the example of my cross browser InputKeyFilter code in which the user can enter a period or comma as a decimal separator, depending on the settings of the user system.
