Missing fonts when exporting to PDF

[chblondel]

Hello,
When exporting my project as a PDF, I get a warning message about missing fonts possibly leading to quality issues (indeed happening).
It says that the following fonts cannot be found: gimpfont229, gimpfont640, gimpfont882. See attachment.
I could not find any related article, nor could find the fonts themselves.
Would you have any clue?
Thanks for your support.

I have never seen anything gimpfontxxx either. Do the font layers show correctly and what fonts are you using in the image before exporting ?

No attachment, so try again. Can you give more details, maybe a screenshot of Gimp showing layers / tools and tool options.

Sorry, I cannot add attachments, "Bad Request Your browser sent a request that this server could not understand." when I try to do it.

The fonts I am using are: 
- Niagato - Personal Use Regular
- Manga Temple Regular
- Comic Sans MS Regular

If I do not tick "convert text layers to image", the part using Niagato - Personal Use Regular appears as slightly shifted.

A quick look around and some references to missing fonts but in other graphics applications.

Do you use accented or foreign characters ? I seem to remember that Gimp 3 now used font-sub-types or maybe it is a code page issue.

Are you exporting several pages in the PDF ? (Manga - thinking maybe a comic )

You could try a test,
Save your work as a Gimp .xcf file (to keep safe and for future use)
For each text layer, Layer -> Discard Text Information.
Export as a PDF.

Does that export ? Probably not what you want but shows that PDF works.
