Control+Backspace inserts a character instead of deleting a word.

[pog5]

Control+Backspace inserts a character instead of deleting a word on seemingly all text fields in the program.

Steps to reproduce:

1. Open any archive in NanaZIP
2. Click the Extract button (either from the Menu bar (2nd item) or from the Copy To... option in the right-click menu)
3. In the Copy to: path input box, press Control+Backspace while you have the box selected.
4. The prorgram inserts the character � (%7F in URL format, also known as Unicode U+007F "Delete")

Expected behavirour:
NanaZIP should delete the path from your current cursor position to the nearest (back)slash lefwards of it.

What's weird is that this functionality already works if you use Control+Delete instead.
