reproduced with Inkscape 0.47+devel r9294 on OS X 10.5.8
Note: AFAIU it is not a clipboard issue (x11 preferences are set to allow correct c&p in Inkscape): the glyphs are incorrect/missing only with Apple's glyph fonts (Wingdings, Webdings{,2,3}). Other glyph fonts like OpenSymbol (from OpenOffice.org) work as expected.
