> Unicode encodings for GID 8712: List(U+f967)
> Unicode encodings for GID 8712 from table (platformId = 0 encodingId = 3):
> List(U+4e0d, U+f967)
> Unicode encodings for GID 8712 from table (platformId = 0 encodingId = 4):
> List(U+f967)
> {noformat}
> I made some java code to reproduce this:
> {code}
> File fontFile = new File("NotoSansSC-Regular.otf");
> OTFParser otfParser = new OTFParser(false);
> OpenTypeFont otf = otfParser.parse(fontFile);
> CmapLookup unicodeCmapLookup = otf.getUnicodeCmapLookup();
> List<Integer> charCodes = unicodeCmapLookup.getCharCodes(8712);
> System.out.println(charCodes);
> CmapTable cmapTable = otf.getCmap();
> CmapSubtable unicodeFullCmapTable =
> cmapTable.getSubtable(CmapTable.PLATFORM_UNICODE,
> CmapTable.ENCODING_UNICODE_2_0_FULL);
> CmapSubtable unicodeBmpCmapTable =
> cmapTable.getSubtable(CmapTable.PLATFORM_UNICODE,
> CmapTable.ENCODING_UNICODE_2_0_BMP);
> List<Integer> unicodeBmpCharCodes = unicodeBmpCmapTable.getCharCodes(8712);
> List<Integer> unicodeFullCharCodes = unicodeFullCmapTable.getCharCodes(8712);
> System.out.println(unicodeBmpCharCodes);
> System.out.println(unicodeFullCharCodes);
> {code}
> A look in the tables with DTL OTMaster 3.7 light shows there are indeed two
> entries. A search for them (in hex) shows the characters 不 and 不.
