Not relevant
>Description:
The implementation of the
'y' command relies on the fact, that all input charactes have
positive value. If fed with a character with value beyond 127 it
is interpreted as a negative index to the constructed translation array.
>How-To-Repeat:
echo á | sed -e y/á/a/
Youy won't get the expected 'a' as output (probably a 0-byte instead).
