Christoph Gohlke has an extension module based on PDCurses [1]. The
good news for Python 3 users is that it uses the [W]ide-character
console API, such as ReadConsoleInputW. Also, its _get_key_count [2]
function is designed to support the alt numpad event sequences that
the system creates for the input filepath when dragging a file into
the console. In my limited testing, dragging filepaths from Explorer
worked without a hitch using a random Latin-1 name "¨°¸ÀÈÐØàèðø" and a
Latin Extended-B name "ƠƨưƸǀLjǐǘǠǨǰǸ".

Unfortunately the Python 2.7 version is linked against the [A]NSI API,
which maps each Unicode character to either the closest matching
character in the console's codepage or "?". Moreover the PDCurses code
has a bug in narrow builds in that it returns the UnicodeChar from the
KEY_EVENT_RECORD [3] instead of the AsciiChar (the name is a
misnomer). In this case the high byte is junk. You can mask it out
using a bitwise & with 0xFF.

That said, IIRC, the OP wants to avoid using any frameworks such as
curses or a GUI toolkit.
