+// Copied and trimmed down from https://github.com/golang/go/blob/e3769299cd3484e018e0e2a6e1b95c2b18ce4f41/src/strconv/quote.go
+// We want to use the standard library's private "quoteWith" function rather than write our own so that we get robust unicode support.
+// Every private function called by quoteWith was copied.
+// There are 2 modifications to simplify the code:
+// 1. The unicode.IsPrint function was substituted for the custom implementation of IsPrint
+// 2. All code paths reachable only when ASCIIonly or grphicOnly are set to true were removed.
