Thanks for your patience. We have investigated the issue and found it is not a bug of Aspose.Words, but a problem with the barcode font.
The font used in the document(‘3 of 9 Barcode’ by CAIL Systems Ltd.) has errors that prevent it from being loaded by Internet Explorer. Aspose.Words exports only a subset of the font, but even if we replace the font file generated by Aspose.Words with the original file downloaded from the Internet, Internet Explorer still not loads it correctly. Additionally, the font validator tool (https://github.com/HinTak/Font-Validator) also reports many errors for the original font file.
