Thanks for helping, Davide.
Massimo, I'm marking this as "notabug" and closing the auto-filed issue.

Good morning,

the file contains "8.25F, \n". I notice a strange behavior with this line:

sed -i -r 's/([0-9])F([,; \]\}\)])/\1\2/g'  file

while I'm expecting to get "8.25, \n", the content is not changed. To get the expected substitution, I must use:

sed -i -r 's/([0-9])F([,; \}\)])/\1\2/g'  file

as if it is not legal to use the escaped character  ']'.

Thanks for your time; I apologize if I'm wrong.

Best Regards
