On Precise (Kubuntu 12.04), if I open up charmap and go to the block "Miscellaneous Symbols and Pictographs" (U+1F300 - U+1F5FF), all but 4 of the characters are missing a glyph (that is, there is apparently no font to render them, so it's the "01F3AC"-in-a-box instead). (The 4 characters are U+1F42D, U+1F42E, U+1F431, U+1F435.)

Where can I get a font that contains glyphs for all of (or even most of) the characters in this block? The other "Miscellaneous..." blocks are all also missing numerous glyphs. Are there any fonts that have all these glyphs?
