Fix Unicode decoding issue with accented characters and special symbols

[B16f00t]

This pull request addresses the issue with accented characters and special symbols in file paths during the drag-and-drop process.

Changes made:

• Modified the py_drop_func to handle Unicode decoding errors.
• Initially attempts to decode the file path using UTF-8 encoding.
• If UTF-8 decoding fails (e.g., due to accented characters), it falls back to Windows-1252 encoding.

This fix ensures that file paths with characters like á, é, í, ó, ú, ñ, and others are handled correctly without causing errors.

This should address and close Issue #42.

For some reason it doesn't work well with some characters like ă, ș and ț. Using the same code from #42 and trying again to drag the folder named ăâîșț to the tkinter window, I'm getting this output:

['C:\\Users\\lenovo\\Desktop\\aâî??']

And normally I should get

['C:\\Users\\lenovo\\Desktop\\ăâîșț']

I think this fix is wrong because you can't assume that the encoding for fallback is 'Windows-1252', for example in Chinese Simplified Windows, the correct encoding is 'gbk'.

In fact, just use create_unicode_buffer and DragQueryFileW, so that the string obtained is unicode.
