It doesn't matter whether the file has the extension "JPG" or "JPEG". Just tested here again. Please upload a sample image in which no tags can be written.

thank you.
i found that digicam windows cannot recognize certain characters
such as below, and that is why writing metadata always fail.
and such files with invalid filename for digikam are likely to be displayed as "JPEG".

for example:
‼︎.jpg
Comment 3 Maik Qualmann 2020-04-26 06:44:51 UTC 
Yes, all characters in the file name must be within the current code page. We don't have a solution for that yet. All libraries used by digiKam must use Windows UTF16 internally.
