It's not just about localising setup pages; we end up dealing with
arbitrary input from the OS and, ultimately, the user in this form too,
don't we? In environment variables and other input/output.

I've seen at least one suggestion which would have the bootloader (and
hence UEFI) handling characters outside the Basic Multilingual Plane,
albeit somewhat tongue-in-cheek: https://lwn.net/Articles/545741/

But you're right that the immediate practical impact of changing it to
be UTF16LE instead of UCS2LE would be almost zero. That's what makes it
a practicable suggestion. rather than simply an "oh, I wish we hadn't
done this". You'll note I'm *not* suggesting we switch to UTF-8, even
though I wish we could.

But it *does* seem like it would be sensible to follow the Windows
example, and retroactively declare "oh, we meant it was UTF16LE all
along; you just never noticed". And then we *remain* consistent with
Windows — and the strings it hands to UEFI, and the strings we hand back
to it, will be interpreted correctly even if someone *does* include a 😻
in them.

That's an orthogonal issue. In fact, emacs seems to cope automatically
with the .uni files. I didn't even *notice* they were in a weird format
until I ran 'git diff' and it treated the file as a binary instead of
text. So yes, it might be nice to have the source code of the .uni files
in EDK2 as UTF-8 and converted as necessary at build time or whatever,
but that isn't what I was suggesting — and I haven't looked at *how*
they get processed to see if that's even a sane thing to talk about.
