Grid cell type: number error

Modify the data entered in the cell in the grid.
If the cell type is numeric and the data you enter is Korean, an error will occur.
What should I do to prevent errors from occurring even if I type in Korean?

Hello @RangRang ,

I tried to reproduce the issue, but in my case the Grid isn’t produces an error, here is config I tried:

const grid = new dhx.Grid(null, {
    columns: [
        { id: "month", header: [{ text: "Month" }], editable: false },
        { id: "company A", type: "number", header: [{ text: "Company A" }] },

    editable: true,
    autoWidth: true, 
    data: dataset

And here is dataset with few Korean numbers:

	const companiesData = [
        { month: "01", "company A": "하나", "company B": 52, "company C": new Date(), },
        { month: "02", "company A": 5, "company B": 33, "company C":  new Date(), },
        { month: "03", "company A": "하나", "company B": 30, "company C":  new Date(), },
        { month: "04", "company A": 30, "company B": 11, "company C":  new Date(), },
        { month: "05", "company A": 27, "company B": 14, "company C":  new Date(), },
        { month: "06", "company A": 32, "company B": 31, "company C":  new Date(), }
