That failed for me. The parser considered it a language object, an R name.
Here's what I needed to do:
> string <- `"this string has both "'" and
'"'`
Error: object '"this string has both "'" and
'"'' not found> string <- deparse(`"this string has both "'" and
'"'`)
Error in deparse(`"this string has both "'" and
'"'`) :
object '"this string has both "'" and
'"'' not found
But success with:
> string <- deparse(substitute(`"this string has both
"'" and '"'`))
> string
[1] "\"this string has both \"'\" and
'\"'"
With linefeed:
> string <- deparse(substitute(`"this string ...
+ has both "'" and '"'`))> string
[1] "\"this string ...\n has both \"'\" and
'\"'"

Forward-slashes are not going to have any desirable effect. They are not the R
escape-character.
Best of luck. I do not think we yet know in what form this "string"
exists at the moment. And it's not clear whether your use case requires
keeping these lines all in one element of a character vector. Generally
`readLines` and `scan` (and by extension all the read.* variants) wiill
interpret the line-feeds as end of line.

[1] "\"this string ..." " has both
\"'\" and '\"'"
Warning message:
In readLines("test.txt") : incomplete final line found on
'test.txt'
