Does LibreOffice Writer support Unicode characters > U+FFFF , i.e. those in planes other than zero? My particular current problem is that I would like to include 𝒩 (U+1D4A9, Mathematical Script Capital N) from the Unicode Mathematical Alphanumeric Symbols range, but LibreOffice just displays "? " (including the space). I have the requisite font support for this, for example in DejaVu Sans, and the character displays in other applications such as Firefox, but I can’t get it to display in LibreOffice. I’m on Windows 7, if that makes a difference.
What happens if you copy this symbol from Firefox to Writer?

It works on Ubuntu Linux, press Ctrl+Shift+u, then type 1d4a9 and press Enter. On Windows the equivalent is holding Alt while typing 1d4a9 and releasing Alt.
What @mahfiaz has answered is correct i.e., if you have font support any character from the Unicode planes can be displayed. For clarification though it sounds like you may not have font support. The latest release of DeJaVu Sans is v2.33 dated 28 February 2011. It does not include Mathematical Script Capital N (U+1d4a9) as can be shown by examining the font. This is supported by what it says in the status.txt file, which skips from U+1d49b to U+1d538.
