Title: fix #1

The bug is: mb_convert_encoding() takes a 3rd argument ($from_encoding), which defaults to mb_internal_encoding().
So Fastimage is dependent upon the currently runtime configured internal encoding.
Converting to "8bit", has no effect, except removing high-ASCII character when from encoding is UTF-8.
So, just removing seems the right fix.
