Hi, I am suddenly getting corrupted comments too. Having used iCash for years - I suddenly now have some transactions with all sorts of strange characters in the comments, and other transactions with comments that look like bits of other comments joined up.
I've tried to do the usual stuff of checking the data etc.... It reports no errors at all.
I'm finding this very worrying as I totally rely on iCash and it seems my database is corrupt in some way - even if it only appears to be the comments at this stage.
iCash uses a SQL database with unicode UTF-16 encoding. This is internal to the library actually. You can rename the document with the '.vdb' extension and open it with the tool listed [URL https://valentina-db.com/en/valentina-studio-overview]here[/URL] (free version) and see what encoding you get for those comments.
Note that it is the very first time I hear about such problem.
To repsond to your question, yes, you can re-import a XML file and recreate the document.
