Looks like RPE/Aspose does not substitute another “best matching” font when the set font family is not found. We can see that all fonts are replaced by same ‘Abyssinica SIL’ font, though there are several fonts available in RHEL.
We get the below log:
CRRPE1064I Finalizing document generation. Writing output files…

Thanks for your inquiry and sorry for the delayed response.
Yes, this is correct i.e. currently if Aspose.Words cannot find a font with the exact name match, it attempts to select the most suitable font from all of the available fonts as a substitution. However, we’re glad to inform you that recently we’ve implemented a functionality where users will have the freedom to provide a substitution font of their choice to the rendering engine. This feature will be available in the next version of Aspose.Words i.e. 11.1.0 and which is planned to be released by the end of this month. Your request has been linked to this feature and you will be notified as soon as it is available.
Please let us know if you need more information, we are always glad to help you.
But I did not understand why all not found fonts were replaced by the same font “Abyssinica SIL”. I don’t think these different fonts are all matched with “abyssinica SIL”. We expect different fonts can be replaced by different best matched fonts. Please clarify.
For the new feature can allow users themselft to select font subsitition, I wonder how to use this feature?
Hi
Thanks for your request. If some font used in the document is not installed on the PC where you are performing conversion to PDF. Aspose.Words uses an alternative font. Aspose.Words selects the fonts according to the following process:
a. Aspose.Words tries to find the required font among the fonts embedded in the original document. Some document formats such as DOCX can contain embedded fonts.
b. Next, Aspose.Words tries to find a font on the file system with an exact font name match.
c. If Aspose.Words cannot find a font with the exact name match, Aspose.Words attempts to select the most suitable font from all of the available fonts.
d. Finally, if Aspose.Words cannot find any fonts on the file system, it renders the document using the free Gentium font that is embedded into the Aspose.Words assembly.
Best regards,
We have set 6 different fonts name to one document:
Liberation Sans
Arial Unicode MS
Liberation Serif
Liberation Mono
Comic Sans MS
Times New Roman
Run the document generation on both RHEL and Windows, we get different logs:
doc gen(on Windows):

Also some warnings are conflicting.
CRRPE3555W PDF warning: Font ‘Arial Unicode MS’ has not been found. Using ‘Times New Roman’ font instead.
CRRPE3555W PDF warning: Arial Unicode MS font is used in the document. Line spacing could be rendered differently.
When ‘Arial Unicode MS’ font is not used, the last warning should not be shown.
Please advise.
All different fonts are replaced by the same font on both RHEL and Windows, so I don’t think the font subsitution work well?
Thanks for your inquiry and sorry for the delayed response.
Please note that, different Linux distributions store fonts in different folders. Aspose.Words looks for fonts in several well-known locations. By default, Aspose.Words looks for the fonts in the following locations:
/usr/share/fonts
/usr/local/share/fonts
/usr/X11R6/lib/X11/fonts
This default behaviour will work for most Linux distributions, but not guaranteed to work all of the time. You might need to specify the location of true type fonts explicitly. For this, FontSettings.SetFontsFolder method is used to indicate where Aspose.Words should look for fonts. When a valid path is passed to this method, Aspose.Words no longer looks in the registry but it only scans for fonts within the specified folder.
