It's not just allocInitFromFile, I'm looking at the other callers of
image_find_image_file and they all call ENCODE_FILE after it too.
The only direct caller of image_find_image_fd that actually uses the
contents of the returned string (svg_load) also encodes the file name.
So I think we could restrict the use of the encoded filename within
image_find_image_fd to *only* when it actually opens the file.
Patch attached. I've tested it here but I only have a couple of images
to try it with.
I've been looking at the other changes I made in
747a923b9a35533f98573ad5b01fccf096195079 and I'm not sure they're
correct. They clearly work now, but most of the time it's probably
simple ASCII which should pass easily.
Before they *all* seem to have assumed the data was UTF8 encoded,
which is surely wrong since most of the time it's coming from Emacs.
It's things like menu item titles.
These are the use cases stringWithLispString was designed for, right?
The only odd one is image filenames because they're explicitly encoded?
