Hello all,
I am not sure if the problem here is necessarily the same as SABANO's, but here is a sample document. In conclusion, the problem depends on whether the driver mode is GDI or XPS, and which Japanese font is used. As indicated in the following verification, the combination of certain fonts (e.g. MS Mincho) in combination with the XPS driver mode can sometimes be displayed correctly (see page 2 of attachment "checklist - MsMincho.pdf"). However, on the whole, it is rare that they are displayed correctly.
In the following verification, I pasted the Japanese sample text (sample.txt) into the latest version of Microsoft Word, changed the font to each of MS Mincho (MS 明朝) and Yu Mincho (游明朝), and output PDF files using the following five methods.
- PDF-XChange Printer Standard - Driver mode : GDI (default)
- PDF-XChange Printer Standard - Driver mode : XPS
- Microsoft Word Export menu
- Microsoft Print to PDF
- Adobe PDF (Acrobat X)
These fonts are included as default in the Japanese version of Windows 10/11, but even if you are using a non-Japanese version of Windows, they will be installed by adding the Japanese language pack.
- Japanese Supplemental Fonts - https://learn.microsoft.com/en-us/typography/fonts/windows_11_font_list#japanese
- BIZ UDGothic
- BIZ UDMincho Medium
- Meiryo
- MS Mincho
- UD Digi Kyokasho
- Yu Mincho
Please see the following PDF files summarizing the output results for each font, with the problem areas highlighted with yellow markers, respectively, in the root directory of the attached files.
- checklist - MsMincho.pdf
- checklist - YuMincho.pdf
Note that the base contents of the checklist have been rasterized to avoid differences in display depending on the file viewing environment. The original output files are saved in a subfolder of each font name. I performed this verification after creating a new Windows account, so not only the PDF-XChange Printer Standard settings, but also Microsoft Word, Acrobat PDF, and all other settings are default settings.
As a representative example, please refer to the following two output results when the font is set to MS Mincho, which can be compared with a GIF animation.
- PDF-XChange Printer Standard - Driver mode: GDI
- Microsoft Word Export menu

- Characters marked in yellow are not displayed correctly.

Note that I have also reported a problem with vertical writing in the following topic.
- PowerPoint files containing Japanese vertical writing are not converted to PDF correctly.

Hoping that the above information will be of some help to you.
Thank you so much for your continued support.
