Not sure about this. Most other applications on this PC will display the
two countries' flags, as desired, eg Writer, web-browser, even xed
(basic text editor).

Accordingly, took @Cameron's advice. Leading to:

Gnome Terminal: won't display "\U0001F1F3\U0001F1FF" (etc)
Terminator: won't display
Tabby: doesn't seem to load from (rpm) repo
RoxTerm: no choice of fonts, won't display
rxvt: won't compile, gave-up fighting unfamiliar requirements
Terminology: offers choice of fonts, but still fails

Kitty: works!


Kitty is not something I've come-across before. Its write-up says
«
Kitty is a free, open-source, and fast, feature-rich, GPU accelerated
terminal emulator for Linux, that supports all present-day terminal
features, such as Unicode, true color, text formatting, bold/italic
fonts, tiling of multiple windows and tabs, etc.

Kitty is written in C and Python programming languages, and it is one of
few terminal emulators with GPU support

Yes, the one that 'works', is using the same fonts as (say) Writer, and
the original (Gnome) Terminal that fails.


Please don't take this as a scientific survey. I didn't spend any time
investigating - either the s/w worked or it didn't! However, a terminal
is doing a simple job (at the user-level), so there's not much to them
in terms of knobs to twiddle or levers to pull.
