While things are much improved with HarfBuzz and moving the font handling into CommonSalLayout. But I'm still not sure this is correct, at least not in handling digraphs for the Graphite fonts. When LO exports to PDF the mapping of "The fire flying coffee left Quickly.", with Graphite font(s), the /ToUnicode stuct is getting an additional glyph added to the digraphs (both PUA and , and then is not mapping that glyph when it probably should. Use the below /ToUnicode chart with annotations, and read out the Tf[.*]TJ text runs (from LO 6.2.1) in <a href="show_bug.cgi?id=124191#c16">comment 16</a> <01> <005400680065> --> "The", but maybe should be just "Th"? x <02> -- "e" not mapped <03> <0020> -- <sp> <04> <006600690072> -- "fir", but maybe should be just "fi"? x <05> -- "r" not mapped <06> <0066006C0079> -- "fly", but maybe should be just "fl"? x <07> -- "y" not mapped <08> <0069> -- i <09> <006E> -- n <0A> <0067> -- g <0B> <0063> -- c <0C> <006F> -- o <0D> <006600660065> -- "ffe", but maybe should be just "ff"? <0E> <006C> -- l <0F> <006600740020> -- "ft<sp>", but maybe should be just "ft"? <10> <005100750069> -- "Qui", but maybe should be just "Qu"? <11> <006B> -- k Seems consistently incorrect. A logic flaw in building the map(s)? Would that be our pdfwriter_impl, or now the grapite2 hb shaper?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
