Created attachment 112514 [details] Test file There several possible ways to encode characters for use with Symbol font: 1. Use 8-bit ASCII codes: U+0020..U+00FE range (λ = U+006C). 2. Use Unicode codes (λ = U+03BB). 3. Use Unicode private range: U+F020..U+F0FE (λ = U+F06C). All this methods works fine in Ubuntu 14.10 + LibreOffice 4.3.3.2. But with Windows 7 SP1 + LibreOffice 4.5.0.0 master @ ee21771d, half of Symbol's ASCII range is rendered as empty rectangles. I think it's a bug. Attaching test file and it's screenshots.

Also tested with Ubuntu 14.10 + LibreOffice 4.5.0.0 master @ 07e84cae - works well, same result as with Ubuntu 14.10 + LibreOffice 4.3.3.2
