How Do I Replace All Xa6 In My Code

I obfuscated my python 3.5 code and now I am left with these strange black boxes. I am not able to copy them and 'search and replace' with some character. How am I supposed to get

Solution 1:

If you use Notepad++, you can use the HEX-Editor plugin and view the raw hex of your source, and then use Ctrl+H to find and replace "A6" with whatever you desire.

If you do not have that plugin, it's very easy to download it using Notepad++'s built in plugin manager.

The extended ASCII Tables tell me that 0xA6 is a broken vertical bar, which certainly doesn't seem like a valid character for an identifier, so no questions there.
