I have better results than you but still not perfect...
I mean, all the symbols are correctly rendered in LibO except the "OK hand" symbol at "B" position which shows up as a rectangle in 4.2.x and as a bullett in 4.3.x

so I set status to NEW and platform to ALL
Comment 4 Ofir 2015-02-06 00:55:05 UTC
Same problem with LO (Ubuntu 14.04)
Comment 5 A (Andy) 2015-04-03 19:09:23 UTC
Reproducible with LO, Win 8.1 (result as in comment 3 mentioned)
Comment 6 Yogesh Bharate 2015-04-07 09:41:32 UTC
- This is reproducible on latest build also.

- This issue is due to the wingding and wingding2 unmapped symbol in OpenSymbol.

- LibreOffice uses OpenSymbol which is  metric-equivalent to Microsoft's windings and wingding2.

- While rendering LibreOffice mapps Symbols of wingdings & wingdings2 in OpenSymbol font.

- If symbol is not present in OpenSymbol font then while rendering LibreOffice put a rectangle instead of symbol.

- This mapping of symbols handles in fontcvt.cxx (/core/unotools/source/misc/fontcvt.cxx)

- This is OpenSymbol font issue, to solved this required more information about the OpenSymbol font.i.e. OpenSymbol character set and its equivalent character Unicode.
