IsAlpha - The string should contain at least one alpha (in the language charSet specified) and consist only of alpha. Also, the string should consist only of alpha and numbers. IsAlphaNumeric - The string must contain at least one alpha (letter in Unicode range, specified in charSet) and at least one number (specified in numSet).
