[BUG] Seems like output dir tree printing in dcm2bids_scaffold assumes UTF-8 encoding which breaks logging on windows

[kenanoestreich]

The core function of dcm2bids_scaffold seems to still be working fine by inspecting the files and directories.

I ran dcm2bids_scaffold -o ~/bids_dir on git bash on Windows 11, and I received a logging error for each file or directory created; each looked like this, with small changes depending on which file or directory it tried to log.

Not a big issue, but might be solved if you can figure out the unicode encoding of the native system. Not sure how all that works.

Here's the error:

--- Logging error ---

Hello @kenanoestreich ,

Thank you for reporting this issue.
Can you give a try with the container ? I would be interested in knowing if you get the exact same error with it.

In the meantime I need to find a laptop with Windows 11 now 😅
