sed error, why?

Question

bash

Hello. The essence of the problem: if run through sh s.sh script works
through cron - no.
mistake:

sed: -e expression #1, char 73: strings for `y' command are different lengths
sed: -e expression #1, char 73: strings for `y' command are different lengths

How to fix?
Thanks

Answer 1

the most common you stupidly specified /scrypt.sh
but in cron there is no $PATH by default
, you need to specify the path to the interpreter
/bin/bash scrypt.sh
, better show what you have in the cron

Answer 2

I think a certain locale is set in the user profile, which allows you to work normally with the encoding, but it is not set through crontab.
Look again at your .profile, .bashrc and configure the same for cron.
