Error code 404 : When Overwriting a Sharepoint column that contains space before '/' in it's name

I have created a SharePoint List with column name that contains space before '/'. Ex: "ABC /DEF"

When I am trying to overwrite the same column it fails with Error . Response code: 404.

So does it have anything to do with column name? Are there any guidelines on creating column name with special characters (including space, '/') in sharepoint list?
