I've been using a slightly different syntax but I forget where I got it:

% !TEX encoding = UTF-8 Unicode
% !TEX TS-program = LuaLaTeX

Could someone please point me at the definitive source?

Could be TeX processing directives from editors like
TeXShop or TeXworks.

Yes, there is partial or full support in many of them, but I don't see anywhere that lists the full set independently of the editors, except
the tex.se page at https://tex.stackexchange.com/a/84687/36296

Thank you; missed that.

Does anyone know of support for these magic comments in Emacs?

That is editor-dependent, I am not aware of
any standards. I use them mainly to inform my
publisher what I have been doing, so these
magic comments are for humans rather than for
the computer. But WinEdt understands at least
the mode command.

OK, thanks.

I haven't managed to find anything on their web site about this yet.

<https://www.winedt.com/doc/QuickGuide.pdf>,
section "3.4 TeX and UTF-8", mentions so-called "pragma-comments".

<https://www.winedt.com/doc/QuickGuide.pdf>,
section "3.5 Modes and Submodes", says:

| Instead of setting such modes through the Document Settings dialog or
| adopting a practice to name your files with more than one filetype
| (e.g. Paper.fr.tex) it is possible to enter submodes (as comments) in
| the first (or second) line of a document. WinEdt modes can be
| specified as a comment:
|
| % !Mode:: "Mode:Submode:Submode"
|
| WinEdt also recognizes mode specification as used by emacs:
|
| % -*- mode: TeX -*-
| % -*- coding: utf-8 -*-
|
| It is also possible to specify mode and submode in a single comment:
|
| % -*- TeX:DE:Soft:UTF-8 -*-
|
| However, as Emacs might not recognize such specifications, it is
| better to use WinEdtrCOs convention !Mode:: "TeX:DE:Soft:UTF-8" as
| described above.
