How can I check if the numbers contains arabic numbers in a list of string

Problem Description:

I have a list of strings , which may contain english numbers and arabic numbers.

What I need to do is to convert arabic numbers in to english numbers.

for which I am using the below code .

private string toEnglishNumber(string input)
    {
        string EnglishNumbers = "";
        for (int i = 0; i < input.Length; i++)
        {
            if (Char.IsDigit(input[i]))
            {
                EnglishNumbers += char.GetNumericValue(input, i);
            }
            else
            {
                EnglishNumbers += input[i].ToString();
            }
        }
        return EnglishNumbers;
    }

Now I need to make sure before passing my string in to this function that string contains the arabic numbers for example :

List of strings :

[
    "٠٥٥ ٥٣٠ ٨٦٨٤" , "+966557864894"
]

So instead of passing both string , I just need to pass only 0 index string which contains arabic numbers , how can I do it.

You can use this method:

public static bool HasArabicGlyphs(string text)
{
    foreach (char glyph in text)
    {
        if (glyph >= 0x600 && glyph <= 0x6ff) return true;
        if (glyph >= 0x750 && glyph <= 0x77f) return true;
        if (glyph >= 0xfb50 && glyph <= 0xfc3f) return true;
        if (glyph >= 0xfe70 && glyph <= 0xfefc) return true;
    }
    return false;
}

List<string> arabicStrings = stringList.FindAll(HasArabicGlyphs);
