Import KOReader epub annotations: incorrect Chinese/CJK characters in notes

shan.lu · 2026-04-25T17:35:57+00:00

In Zotero epub viewer, File - Import Ebook Annotations, select the metadata.epub.lua file with annotations in Koreader.

The importer works well, all the highlights locate correctly. The only problem is, all the Chinese characters in the annotation note become unrecognizable.

metadata.epub.lua of Koreader is UTF-8 encoded and all the CJK characters are readable in .lua file.

Can you please send the metadata.epub.lua to support@zotero.org and include a link to this thread? (May need to ZIP it to get it to go through, depending on your email provider.)

Wonderful. Thanks a lot.

ps. since we have importing, is there any plan to export the highlights and annotations in zotero epub to.lua or .json? It would be amazing for the whole epub readers community.

Annotation export is planned, yes.
