byte[] datas = File.ReadAllBytes("d:\\original.docx");
var doc = new Aspose.Words.Document(new MemoryStream(datas));
var options = new Aspose.Words.Saving.PdfSaveOptions();
options.DownsampleOptions.Resolution = 200;
doc.LayoutOptions.RevisionOptions.ShowRevisionMarks = false;

@wengyeung The problematic character is ‘LATIN SUBSCRIPT SMALL LETTER N’ (U+2099). The glyph for this character is missing in “Arial” font and Font Fallback is performed. Both Aspose.Words and MS Word selects “Cambria Math” fallback font for this character. It seems that this font is not available to Aspose.Words on your side. For the same rendering as in MS Word, you should provide the “Cambria Math” to Aspose.Words. Or alternatively you could select a different fallback font and update fallback table accordingly. As an option Aspose.Wrods provides predefined fallback table for free Google Noto fonts.
