There's no reason this string should fail:
"Snug & raw was I ere I saw war & guns."
when returned as:
".snug & raw was I ere I saw war & gunS"
but the evaluator for Golang escapes the result as:
".snug \u0026 raw was I ere I saw war \u0026 gunS"
I tried all the escaping mechanisms to get this to pass, but none helped. Looks like a Leetcode bug.
