Resolution: Fixed
> App crashes when translating string with certain Unicode characters

> Key: GEODE-9412
> URL: https://issues.apache.org/jira/browse/GEODE-9412

> tl;dr, we're not translating unicode correctly between .net and C++.
> When a unicode string comes into the CLI layer, we use
> `marshal_as<std::string>` to translate, then assume this yields UTF-8. In
> fact, what it yields is a string encoded in a) whatever the local code page
> is for the system, or b) the default code page for the app, if one exists in
> the manifest. In the C++ layer, we then assume the string is UTF-8, and for
> a PUT, attempt to translate into Java-modified UTF-8, which ends up throwing
> an uncaught exception when it encounters a character that is not a valid
> UTF-8 start code. When this exception hits the native/managed boundary, the
> app crashes.
> To avoid this issue, we need to `marshal_as<std::wstring>`, then use `std`
> conversion functions to arrive at UTF-8, and pass that down to the C++ layer.
> We also need to use the reverse process when sending strings back up to CLI.
