Strange character set - xml cannot be decoded

[MarcusCalidus]

Could you please hint me to what I am doing wrong?
It looks like a codepage error or something.

using "ews-javascript-api": "^0.10.0",

authenticating with new XhrApi().useNtlmAuthentication(user, password)

upon calling exch.ResolveName('marco')

I get the following error

[1] [1] [xmldom warning]        unclosed xml attribute 
[1] [1] @#[line:1,col:164]
[1] [1] [xmldom error]  element parse error: Error: invalid tagName:[^�w

Raw XML fed into EwsXmlReader(rawXML) looks like this:

thank you. Setting exch.AcceptGzipEncoding = false; did help
