It looks like the file contains text which is neither ASCII nor Unicode. It'll be the name of a bone or material. You could try opening the file in a text editor and removing anything that appears corrupted.

There was a bunch of characters with like, accents and stuff, should I remove those? I know when my PC locale changed it messed up a bunch of things.

Just installed the Source Tools (latest release) and every time I try to open an .SMD file I just get this
https:// imgur.com/a/nuhI8Yz (put a space in the link I wasn't sure if Steam would let me post a link)
It's annoying me like hell, I can import the .obj fine but the SMD wont work :-( Help
