@yueru We have completed analyzing the issue and decided to close it as not a bug. The issue arises because PCL does not support external fonts. Its internal font set is limited, and if the required font (in this case, SimSun) is not available among the internal fonts, PCL defaults to Arial, which cannot display Chinese characters.
Embedding fonts into PCL is not supported by Aspose.Words.
As a workaround, we can offer you two options:
Convert the document to PostScript, which supports external fonts like SimSun.
Alternatively, you can convert the document directly to PNG, which will preserve the characters as an image.
