Don't use Emojis that often. The colored circles (U+1F534 etc) display
in full, glorious, technicolor.

However, when trying the above, with our local flag in (Fedora Linux,
Gnome) Terminal or PyCharm's Run terminal; the two letters "N" and "Z"
are shown with dotted-outlines. Similarly, the Mauritius' flag is shown
as "M" and "U".

Whereas here in email (Thunderbird) or in a web-browser, the flags
appear, as desired.

Is this a terminal short-coming (locale charmap -> UTF-8 - which brings
to mind the old UCS-4 questions), a font issue, or what (to fix)?

This is the modifier letter mid tone bar, Unicode U+02E7:

. And this is the modifier letter extra-high tone bar, U+02E5:

. Here are both of them inserted by me to directly follow each other:

˧˥

. Some display systems might now have combined them into a
single symbol. It's like magic!

You can also try this code:

print( "\u02E7\u02E5" )

. If they are not combined, I think your display system /
output device just is not capable or willing to combine them.

For another example. This

n̩

is an [n] (pronunciation symbol) marked as being syllabic.
It also is transported as a sequence of two Unicode code points,
which then are hopefully combined when being displayed.

Try this, you guys:

import pathlib
import subprocess

filename = "tmp20211128234439+0100file.html"
path = pathlib.Path( filename )
with path.open( "w", encoding="utf-8" )as file:
print( r'<!DOCTYPE html>', file=file )
print( end=r'<html ', file=file )
print( end=r'xmlns="http://www.w3.org/1999/xhtml" ', file=file )
print( r'lang="en" xml:lang="en">', file=file )
print( end=r'<head><meta charset="UTF-8" />', file=file )
print( r'<title>Main</title></head>', file=file )
print( r'<body><p>', file=file )
print( end="\N{REGIONAL INDICATOR SYMBOL LETTER M}", file=file )
print( end="\N{REGIONAL INDICATOR SYMBOL LETTER U}", file=file )
print( r'</p></body></html>', file=file )

subprocess.Popen( filename, shell=True )

The Popen call is intended to show the HTML file in a modern browser
capable of showing the flag. If it does not work, just go ahead and
open the created file "tmp20211128234439+0100file.html" manually in
a modern browser.
