This function loads a font object from the given file or file-like
object, and creates a font object for a font of the given size.
Pillow uses FreeType to open font files. If you are opening many fonts
simultaneously on Windows, be aware that Windows limits the number of files
that can be open in C at once to 512. If you approach that limit, an
``OSError`` may be thrown, reporting that FreeType "cannot open resource".
This function requires the _imagingft service.
:param font: A filename or file-like object containing a TrueType font.
Under Windows, if the file is not found in this filename,
the loader also looks in Windows :file:`fonts/` directory.
If the file is not found in this filename, the loader may also
search in other directories, such as the :file:`fonts/`
directory on Windows or :file:`/Library/Fonts/`,
:file:`/System/Library/Fonts/` and :file:`~/Library/Fonts/` on
macOS.
:param size: The requested size, in points.
:param index: Which font face to load (default is first available face).
:param encoding: Which font encoding to use (default is Unicode). Common
