I tried reproducing the above issue and can confirm it.

The text is weirdly shaped when opening a binary file with file
extension. There are no messages in stdout/stderr, however.

Description: PNG image

Buffer 1: Opening a image file without extension in its file name.
Buffer 2: A ASCII text file.
Buffer 3: (generate-new-buffer "கட்டற்ற மென்பொருள்")
Buffer 4: The same image as in buffer one but with file extension in
          the file name.

It looks as if the problem is with the file extension and not the file
itself, I might be wrong:
