--- Comment #1 from V Stuart Foote <vsfo...@libreoffice.org> ---
Font fall back/substitution is controlled by the os.

Additionally, if you use a font heavy with PUA, the os font fallback will be
chaotic. Unicode PUA codepoints are meaningless except when explicitly applied
from the font containing them--there is no effective way to control that,
locale or language of the glyph or as assigned to word is not sufficient.

Use a charmap utility, like BableMap on Windows, to explore the coverage of the
font. LibreOffice's Special Character Dialog also works, but the collapsed
character charts are a bit annoying to work with when looking at the PUA glyph
coverage, or a fonts actual BMP/SMP glyphs.  Something not in the font gets os
controlled fallback.
