Cannot extract zip files with filenames using extended ascii characters (ex: ä-char 132, Ü-char 154, and ü-char129) on Android Nougat

There is a bug when trying to extract a file that has a non-English ASCII character in the name starting with Android Nougat. According to Android's Charset, it only handles 7 bit ASCII (below). However, if the filename has 8 bit ASCII (chars 128-255) ExtractManager gets an exception due to the filename's character encoding and it will abort the Zip extraction.

It can be fixed by using the steps outlined in the post below in ExtractManager.extract(File,String) by setting the Charset in the ZipFile instantiation to "ISO-8859-1".

The files will also display with the wrong characters as well, but that is less of an issue.
