If you work with anything other than English, you would earlier or later encounter the characters from the title or just plain ??????????. Encodings are usually known, but sometimes you just get gibberish and need to make sense of it. In this cases [$zcvt](https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=RCOS_fzconvert) is your friend, the three argument form specifically. But there are a lot of options. So here's an utility script to check how the text would look like in different encodings: Zn "%SYS" Set Text = "ÍàØâàÞæØâë" Set Ref = ##class(Config.NLS.Locales).OpenCurrent(.Sc) Write "Locale name: ",Ref.Name, ! Do Ref.GetTables(.Tables) Set Key = "" For { Set Key = $O(Tables("XLT", Key)) Quit:Key="" Write Key," ",$zcvt(Text, "I", Key),!} And here's a sample output: ![](/sites/default/files/inline/images/images/image-20191209120357-1.png) As you can see the correct encoding in this case is LatinC.
