Yes, that's a very old post, indeed.
But the rather simple problem it raises has still not been solved.
When i raised the issue recently (may 2025), Calibre's developer, seemingly quite annoyed, replied that this was a very old issue that has been discussed at length and that I should simply google the subject.
Very well. But why then is Calibre still replacing French accented characters in folder and file names, while correctly storing the author and title data with their proper accented spelling in the opf metadata file ?
The conversion of accented characters to their English equivalent does not happen by magic. Somewhere in Calibre's code, a function processes those names and outputs modified unaccented names. That's not right !
So, why not simply put an end to that stripping/converting ? Because Calibre's search and classify functions would get more complicated? Because the representation of accented characters is not the same across all OS ?
Come on...
