validate string - only specific language characters

Is there a way to check if a string contains characters of a given language only? (for example Japanese, Hebrew, Arabic)

I'm wondering if there is a way implementing this kind of validation in Javascript\Jquery and in c#?

EDIT

I'm not willing to check if the string contains valid words of a specific language dictionary. I'd like to validate that all characters belong to that language.

internal bool HasArabicCharacters(string text)
{
    Regex regex = new Regex(
        "[\u0600-\u06ff]|[\u0750-\u077f]|[\ufb50-\ufc3f]|[\ufe70-\ufefc]");
    return regex.IsMatch(text);
}

@CD, so sure you can do that.

In C#, just:

string str = "this text has arabic characters";
bool hasArabicCharacters = str.Any(c => c >= 0xFB50 && c <= 0xFEFC);

No, you cant check exact language. You can check only those chars which there no in other languages. For example cyriclics, hieroglyphs etc. Like a hint you can use google translate api to define in what lanuage user enters the text.

Maybe using a regular expression with UNICODE charset?
