[BUG] blob not loadable from cache if umlaut is in path

[goeck]

Firing up the demo application via Windows CLI after installing all requirements as given in README (via command "python depthai_demo.py") results in GUI being opened but finally in GUI error message, stating that the blob file can't be found. I assured the blob file is actually existing at the given path.

Steps to reproduce the behavior:

1. Login as user having an Windows allowed german Umlaut (ä,ü,ö)
2. Run demo script "python depthai_demo.py"
3. See error

Is it possible to configure the cache path, so I can move it outside the user directory?

Hi @goeck

Sorry for the issues here - we've just merged in support for UTF-8 paths on Windows as well into the core library. After we make a release, this issue will be fixed.

Regarding moving the cache directory, CC: @VanDavv

Yes, it's possible to change the cache dir. After blobconverter import, please add

blobconverter.set_defaults(output_dir=<path>)

This will make the blobconverter use a specific cache directory instead of the default

@VanDavv Thanks for the hint, maybe you can guide me just a little bit more, in which file to add this in order to make the demo working? That would be awesome. :-)

Sweet. Thanks a mile!
