Comment 11 for bug 873394

Opening the symbol.ttf in fontforge (lots of warnings) and decoding it with ttx shows that the unicode mappings (cmap_format_4) are messed up in this font.

I was able to "repair" it with fontforge with the following steps:

*) open symbol.ttf
*) Encoding->Force Encoding->Symbol
*) Encoding->Reencode->Macintosh Latin
*) File->Generate Fonts... (ignore warnings and save)

Then
*) remove symbol.ttf from whereever it was installed
*) call "fc-cache" as root (-v if you like)
*) copy the new symbol.ttf saved with fontforge to the old path
*) restart the application which displayed the damaged symbols

My "pi" bug 24731 is fixed then.
