Quotes inside $() are independent from the ones outside. If you escape
them, you get literal quotes as part of the filename.

$ echo hello > '"filename"'
$ echo "$(<\"filename\")"
hello

$ echo another > 'name with spaces'
$ echo "$(<"name with spaces")"
another

I've been led to understand this isn't so with backticks, though.
