Very nice! Thanks for the background - that was a good discussion, and nice to understand your
concern about applying NPC treatment to a printing character. There is a case to be made for some
kind of visual discrimination (on the working screen, not the printed page) between typographically
identical glyphs which behave differently, like breaking and non-breaking hyphen.

NPC -- Non-Printing Character 
The LibreOffice VCL canvas will apply "field" shading to a broad class of control and non-printing
characters, we've asked to give them more distinction from fielded values

Excellent! (I was wondering what happened to U+2011 as I investigated the "General Punctuation"
group.) So it's just a matter of the Liberation family not covering the U+2011 codepoint - but a replacement
glyph is provided. Thanks!
You used a term I don't recognize: "NPC". My search turned up that it is a popular abbreviation for "non-playing character"
in domains like WoW, Runelite and lots of other things of which I know nothing, but fortunately I don't think you used it in that context. I
suspect it is close to that textually -- "non" <?> "character" -- but I decided I had best ask: ?

You've missed the one Unicode point that does exactly what you require, but its use will depend on
the font in use.
U+2011 NON-BREAKING HYPHEN
You can enter via LibreOffice Special Character dialog, or LibreOffice's Unicode toggle. That is you can
type U+2011 and then <Alt>+X to toggle the glyph.
If the font in use does not "cover" the codepoint, you'll get a fallback replacement or possibly
the no glyph value for the font.
When added to canvas the non-breaking hyphen character will receive NPC highlighting.
