Hi (we have a paid licence for Aspose.Words 
)
we have a problem when we convert docx to pdf using Aspose 20.8
we have a code like
final Document document = new Document(inputStream);
document.getLayoutOptions().setTextShaperFactory(HarfBuzzTextShaperFactory.getInstance());
synchronized (HARFBUZZ_LOCK_CONSTANT) {
document.save(outputStream, asposeSaveOptions.getPdfSaveOptions());
}
and we are getting :
Java frames: (J=compiled Java code, j=interpreted, Vv=VM code)
J 42011 com.aspose.words.shaping.harfbuzz.HB.**hb_buffer_add_utf8**(J[BIII)V (0 bytes) @ 0x000000000b036767 [0x000000000b036700+0x67]
the error is inconsistent with documents
