This works fine, since Windows interprets both "\" and "/" in 
places (including the functions nginx uses).

When using "\" in nginx configuration, you have to be careful to 
properly escape it, since "\" is also an escape character, and, 
for example, "\n" will be interpreted as a newline character.  As 
such, using "/" is usually easier.

On the other hand, this particular issue does not explain why you 
are seeing the "invalid number of arguments" error, it should be 
"cannot load certificate" with a garbled certificate path instead.

The "invalid number of arguments" error suggests you've typed 
multiple arguments in the directive (instead of just one it 
accepts).  This usually happens if a space character is 
accidentally used where it shouldn't, but in the directives as 
shown certainly there are no extra space characters.

Most likely, there is an issue with the text editor you use, and 
it's somehow inserts some additional non-printable characters, 
such as byte order mark or something like that, and this confuses 
nginx.

What editor do you use?  Is using another one and re-typing the 
directives) makes a difference?  E.g., Notepad is usually 
available on Windows and does not seem to corrupt text files.
