The localization guidelines recommend using UTF-16:
"Note that we generally prefer to use UTF-16 encoded strings for user-visible
text."
https://www.chromium.org/developers/design-documents/ui-localization

but all of the audio device name interfaces in Chrome use std::string. Is it
fine to use UTF-8 for this, or should we switch to UTF-16 for audio device names
across the board?
