apply_dnd does not support file paths containing cyrillic symbols

[Shararamosh]

Whenever I try drag-and-dropping files containing cyrillic symbols into my apply_dnd widgets, I get the following error:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc2 in position 24: invalid continuation byte Exception ignored on calling ctypes callback function: <function apply_dnd.__init__.<locals>.py_drop_func at 0x000001B28D9CC220> Traceback (most recent call last): File "D:\Program Files\Python\Python311\Lib\site-packages\pywinstyles\py_win_style.py", line 205, in py_drop_func drop_name = file_buffer.value.decode("utf-8") ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc2 in position 24: invalid continuation byte

I used Claude Sonnet 4.5 to fix the issue. I don't know how to do pull request, so I'll let Akash handle that.

The issue is that the code is trying to decode the filename using UTF-8, but Windows actually returns filenames in the system's ANSI codepage (or UTF-16). The Korean characters (which was used to test) and special symbols in your filename can't be properly decoded as UTF-8. The fix is to use the wide-character version of DragQueryFile (which handles Unicode properly) instead of the ANSI version.

Why this works:
-Windows has two versions of most API functions: ANSI (A) and Unicode (W for "wide")
-DragQueryFileA returns bytes in the system's ANSI codepage, which can't represent all Unicode characters
-DragQueryFileW returns UTF-16 encoded strings, which create_unicode_buffer handles correctly
-This will now properly handle filenames with Korean characters, special symbols, and any other Unicode characters

Added DND support for ANSI codepage (or UTF-16) filenames: py_win_style.py
