    note: When using newDetectEnglish(), the default is to require 60% words and 75% letters to return a match. The ideal values can vary greatly depending on plaintext length and contents. These values can be tweaked in the isEnglish() function, or when calling isEnglish() eg. isEnglish(cleartext, 50, 80) would require 50% words and 80% letters.
