If you are using Acumatica with a Chinese localization, you will need to make some changes if you intend to print via PDF.
The symptom is that when you print Chinese characters and it is rendered into an external pdf. When you open the pdf the text is not viewable.
In report writer there are a number of templates that supply the report you are editing with pre defined styles. You can load these into report writer as they are configured in a special report. Known as a template
There are at least three that I have seen
1) Internal 2)external 3)report
All these templates have default setting of Ariel
The fix is to change these too
Microsoft JhengHei
You need to go into each template and adjust the style from Ariel to Microsoft jhengHei
Once you change the templates you up load them a report versions to the tenant.
Run the report. The report now with Chinese characters or English characters will properly be readable with an acrobat reader
