Мне нужно обнаружить поврежденный текстовый файл, где есть недопустимые (не ASCII) utf-8, Unicode или двоичные символы.

что я пробовал:

iconv -f utf-8 -t utf-8 -c file.csv 

это преобразует файл из кодировки utf-8 в кодировку utf-8 и-c предназначен для пропуска недействительных символов utf-8. Однако в конце эти незаконные символы все еще были напечатаны. Есть ли другие решения в bash на linux или других языках?
