Details:

There seems to be some inconsistent behavior as far as what the print()
command considers a valid filename, where the -dpng flag  result in errors or
freezing while the -depsc flag prints without a problem. For png files, e.g.


print('~/Downloads/test folder/test.png', '-dpng')


if there are unescaped spaces in the filename, I get the following error


GPL Ghostscript 9.05: Unrecoverable error, exit code 1


and if there are no unescaped spaces but the filename contains '~' then for 

print('~/Downloads/test\ folder/test.png')

I get


#GPL Ghostscript 9.05: **** Could not open the file ~/Downloads/test
folder/test.png .
#GPL Ghostscript 9.05: Unrecoverable error, exit code 1


Most strangely, it will freeze if I have a dash surrounded by two spaces,
e.g., 

print('Users/myUserName/Downloads/test - folder/test.png')

though this works if I escape the spaces with backslashes. 

For eps, on the other hand, everything works regardless of tildes or spaces in
the filename.
