As a library, WebRTC should not assume UNICODE and _UNICODE to be defined globally. This CL explicitly selects wide character functions and types in order to build WebRTC with /UUNICODE and /U_UNICODE. Bug: None Change-Id: Ie4e2bcb4c5c34aee6f68dc7b5b54b76f088ee3e4 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/128904 Commit-Queue: Tommi <tommi@webrtc.org> Reviewed-by: Tommi <tommi@webrtc.org> Reviewed-by: Noah Richards <noahric@chromium.org> Cr-Commit-Position: refs/heads/master@{#27313}
