I believe so. GWT ought to get the string from the browser in UTF-16 ---
as that's what Strings are defined to be. You can then ship it back to
the server, as a String, and it should Just Work. Then you get to do the
charset conversion on the server.

I'm quite willing to believe that there are web browser bugs with all
this. It may be worth verifying that GWT is actually getting a valid
string from the browser (by going through and listing all the codepoints
in the string).
In addition, if Word is using all kinds of whacky non-ISO-8859-1
characters such as unbreaking spaces and quotation marks, then
getBytes() might be replacing them with ? signs --- how is it being mangled?
