[BUG] The Message.FromStackExchange field do not perform as expected when using StackExchange

[bigBron]

In my case fromStackExchange is always false:

const waitComesFromStackExchange = '!'
var wait = "1620719461266218800"
fmt.Printf("waitComesFromStackExchange=%s wait=%s\n", string(waitComesFromStackExchange), wait)

//wait[0]: type = uint8
//waitComesFromStackExchange: type = int32
//string(wait[0]+waitComesFromStackExchange) = 'R'

//await := genWaitStackExchange(wait) // R620719461266218800
fmt.Printf("genWaitStackExchange(wait) = %s\n", string(wait[0]+waitComesFromStackExchange)+wait[1:])

//fromStackExchange = false
var await = "R620719461266218800"
fromStackExchange := len(await) > 2 && await[1] == waitComesFromStackExchange
fmt.Printf("fromStackExchange = %v\n", fromStackExchange)

	func genWaitStackExchange(wait string) string {

	// This is the second special character.
	// If found, it is removed on the deserialization
	// and Message.FromStackExchange is set to true.
	return string(wait[0]+waitComesFromStackExchange) + wait[1:]
