I tried:
strconv.Quote()
strconv.AppendQuote() (weird that this is faster than Quote)
fmt.Sprintf("%q")
scanning for !IsPrint() + bytes.Buffer
scanning for !IsPrint() + strings.Builder (sad that this is not faster than
Buffer)
scanning for !IsPrint() + string addition
```
$ go test -benchtime=5s

Could you not use strconv.AppendQuote
Thanks for confirming. I wrote that function and erased a good bit of the
overhead.
bytes.Buffer for the no-escapes path and strconv.Quote otherwise.

If I find a string with a stray backslash in it (which passes IsPrint()) I
still need to quote.
I dug into the Quote() impl and this seems like the right path. Thanks!

I was thinking the other way. If !IsPrint() then strconv.Quote()

A simple loop calling IsPrint is your best bet. You could then have a custom
implementation of Quote that started at a specified index.

Is there any ready-built function that can tell me whether
`strconv.Quote()` would produce a different string than its input, without
actually running it? Or is there a clearly documented set of rules one
could use to test each rune in a string?
I am trying to avoid allocations, and MOST of th
