Re: [EXTERNAL] [libreoffice-users] Non-breaking dash/hyphen

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: ?
