Japanese not displaying correctly when going from DOC to PDF


Hi I have version 15.1 of Words for .net. I have many Japanese documents that I need to convert from Word into PDF. When I do though, the punctuation is not handled correctly, since they use special punctuation - often times it is leaving it at the start of a line, instead of wrapping a character down before it.

I tried downloading a new version 16.11 as a trial, to see if it fixes it, but the problem only gets worse. In the newest version the lines do not wrap at all (since in Japanese they jam all the characters together).

What can I do? Is this something that can be fixed.

Hi Vanna,

Thanks for your inquiry. Please note that Aspose.Words requires TrueType fonts when rendering documents to fixed-page formats (JPEG, PNG, PDF or XPS). You need to install fonts on the machine where you're converting documents to Pdf. Please refer to the following articles:

How Aspose.Words Uses True Type Fonts

If you still face problem, please embed the fonts inside your input document and share it here for testing. We will investigate the issue on our side and provide you more information. To embed a TrueType font in a saved document in Microsoft Office Word 2016, follow these steps:

  • First, select the File option from the Word ribbon at the top of the screen.
  • From the options bar on the left-hand side, choose Options.
  • A Word Options window will come up. Select the Save option from the banner on the left-hand side.
  • Under Preserve fidelity when sharing this document select the check box next to Embed fonts in the file. Then click OK.


I was using an Open Type font. I have switched to a True Type Font (MS-Mincho), and it does seem to fix some of the problems. However, it doesn’t fix them all.

I have attached an example that shows what I mean.

- The word doc is how things look before Aspose converts to pdf. Notice the 4th main paragraph and how it doesn’t put the period on it’s own line by itself, but wraps one of the Japanese characters down so it isn’t by itself.

- Now take a look at the three pdf’s (each from different versions of Aspose)

Version 15-1, notice how the period in that paragraph is on it’s own line now.

I downloaded newer versions hoping things would be better, but …

Version 16-4, things get worse, nothing really wraps
Version 16-11, same as 16-4

Thanks for taking a look at this!

I see a message posted in Feb of this year (2019) saying this issue is fixed. However when I click the link to the update it sends me to a downloads page for jasper reports?

I am using Words .Net (not jasper reports).

I wanted to confirm that this bug was really fixed for Words.Net and if so, can I get a link to the correct update / version?

Is there any way we could pay to get you to focus on this issue? Right now (and for the past 2 years) we cannot generate PDF documents in Japanese or Chinese because of this issue. We would definitely be willing to upgrade to the newest version if it worked / fixed the problem. Let us know what we can do (if anything) to make this issue a priority.



We are looking into your issue. We will get back to you once there is an update available on it. Thanks for your patience.
