While ISO 8895 - 1 recognize accented letters like Àà Ää Ââ Ãã, it couldn't recognize this acute accent
and it's converted to this sign:
I did some research and find out this acute accent is without any associated base character below. (For more details please refer to https://www.cl.cam.ac.uk/~mgk25/ucs/apostrophe.html). Not sure if this is the reason why ISO 8895 - 1 doesn't recognize this acute accent, but it doesn't really make sense ISO 8895 - 1 recognize only part of the acute accent.
if it is a csv file, you have already tried to change to Unicode UTF-8 the input tool and refresh
Yeah it's a csv file. I tried UTF - 8 but unfortunately it doesn't work. That would convert all accented letters to "?"
