In GSUB tables for lookup type 1, the ADJUST value corresponds to "int16 DeltaGlyphID". But it's parsed as an unsigned integer (type 'S'), so it will have a value like 65535 instead of -1, which means it will break when added to the input glyph index. So it should be read as a signed integer instead. -- Philip Taylor pjt47@cam.ac.uk

Thanks! But... + $count -= 32768 if ($count > 32767); I think that should instead be: + $count -= 65536 if ($count > 32767); -- Philip Taylor pjt47@cam.ac.uk
