What I noticed first reviewing your file is that you have special symbols. In order for them to be imported properly, you should open the file in Notepad and save it using UTF-8.
As for SKUs, they have slashes, but it should not cause the issue. The most likely the issue is caused by import method you are using.
If you need one-time import, you can use Store Manager for Magento tool. It is possible to import the file you have using this tool but with some adjustments. In case you are interested, let me know and I will assist you.
