* don't use icu to convert utf16 here, it may already be de-initialized.
* don't use atexit handler, so we can use _exit on windows
* use _exit() here.
* Fix temporary directory handling
On linux we create a sub directory under the temp directory with our own name and a unique id.
On windows we would only return the configured system temporary directory and not create a subdirectory.
This PR makes windows behave similar to linux.
* Cleanup windows implementation of locating the base temp path
- don't try to create a temporary file. The calling function will try anyways and fail then.
- properly check for unsupported characters and bail out.
