For example, if you try to process a text with "gzip | gunzip" it will throw an error saying that it's not a proper gz data.
After digging a bit deeper I found that the pipe is not a real pipe.
So when you gzip, the output starts with "1f8b", but the extension converts it into "1fefbfbd".
Basically, it most probably converts all values from range of the 128-255 to "efbfbd".
