I would agree, It may look quite expensive. But I just compared it with some other conferences like Oracle, Apple, Google, and I found that all of them cost quite close, even usually bigger.

I want to add, something. I'm Russian, and for us, it cost even much more expensive than for you. And unfortunately, last three years, I participated GlobalSummit and I think I was alone from Russia, except IS. But anyway, if I am not mistaken, last Global Summit participated by more than 200 people from 23 countries, but most of these people from the US.

I don't know how close my version of this method to the original, but it should be something like this. But I think, your version a bit bigger.

ClassMethod Main(cfg As %SystemBase, mode As %String) As %String
{
    set trantabla=cfg.trantable
    set str=""
    set list=$listbuild(72,101,108,108,111,32,87,111,114,108,100,33)
    for i=1:1:$listlength(list) {
        set n=$listget(list, i)
        set hex = $zhex(n)
        set str = str _ "\u" _ $extract("000" _ hex, *-3, *)
    }
    set str=$zconvert(str, mode, trantable)
    set:$length(str)'=12 str="????? ??????"
    quit str
}

Btw, it was a good idea, to deploy code. But I think bad idea to hide original string in $ListBuild 

set list=$lb(72,101,108,108,111,32,87,111,114,108,100,33)

Because, such static variables, stored as is in OBJ code, and could be easily recognized.
