Well, something has changed somewhere (normally, computers don’t change spontanuously). That does not mean you changed something, though.
Anyway, if you only have filenames with plain ascii characters (English), and , ‘_’, ‘-’, you shouldn’t have a problem (so you can click “Yes”). If you have accented characters like ‘éèàç’, you should be ok as well. With less common accents (Eastern European languages) you may end up with files Digikam won’t see, and this is almost guaranteed if you have names with foreign alphabets (Greek, Cyrillic, etc).
That “windows-1252” is what’s called a codepage, or a table indicating which character corresponds to a given 8-bit value.
Thank you !
For us not so techie types, maybe a notice about this near the downloads or on the description page; as, I bet I am not alone in not knowing just what to do.
