> Since the Windows 10 fall creators update all files with the Symbol standard 14 font are no longer rendered properly. Seems to have something to do with a difference in the cmap subtable (all numbers start with F000) and a missing postscript table.
> The font has two cmap subtables. The first one has codes that start with 0, the second one has codes that start with 0xF000. The code names we get from {{getUniNameOfCodePoint(unicodes.codePointAt(0))}} are NOT the low ones, only some match, those that are also in ascii.
> For ">", there are two cmap subtables codes: for "Macintosh, Roman" it is 0x3e, for "Microsoft, Symbol" it is 0xf03e. I tried forcing the first table
> {{code}}
> cmap = cmapTable.getSubtable(CmapTable.PLATFORM_MACINTOSH, 0);
> {{code}}
> but many codes are missing, e.g. the greek alphabet.
> For "eta" (looks like an "n")
> pdf code 0150 = 0x68
> unicode 0x3b7
> windows code in charmap.exe: 68
> code in subtables: 0x68 and 0xf068
> lozenge
> unicode 0x25ca
> pdf code 0340 = 0xe0
> code in subtables: 0x0e and 0xf0e0
> So it seems one has to bypass this unicode thing and work directly with the symbol encoding...
