How to deal with renaming invalid UTF8 characters in directories or files
View rename_invalid_characters_linux.sh
## Reminder to deal with renaming invalid UTF8 characters (if you are using latin-1 also called iso-8859-1)
## Sources: http://unix.stackexchange.com/questions/6460/bulk-rename-or-correctly-display-files-with-special-characters
## To use it, do a chmod +x rename_invalid_characters_linux.sh; and after do ./rename_invalid_characters_linux.sh your_dir_where_you_want_to_scan_and_rename
# First command to add
grep-invalid-utf8 () {
perl -l -ne '/^([\000-\177]|[\300-\337][\200-\277]|[\340-\357][\200-\277]{2}|[\360-\367][\200-\277]{3}|[\370-\373][\200-\277]{4}|[\374-\375][\200-\277]{5})*$/ or print'
