We are using object EnsLib.EDI.XML.Document and the method OutputToString -- ( context.XMLObject.OutputToString("C(utf-8)") ), In the string that we get back, Hebrew characters are unknown and we get question mark instead.
How can we overcome it?
I am seeing the same thing. OutputToString() internally uses OutputToIOStream() but it sets the CharEncoding on the stream to "binary" before passing it. I think this is the source of the problem.
I was able to work around it using OutputToLibraryStream instead:
ENSEMBLE>set msg = ##class(EnsLib.EDI.XML.Document).ImportFromString("<Test>מִבְחָן</Test>")
ENSEMBLE>write msg.OutputToString()
<Test>???????</Test>
ENSEMBLE>set stream = ##class(%Stream.TmpCharacter).%New()
ENSEMBLE>write msg.OutputToLibraryStream(.stream)
1
ENSEMBLE>write stream.Read()
<Test>מִבְחָן</Test>
