pick up last charactor from string

I am using ksh for this program.
But I'd also like to know if there is more than one way to do it.
Even maybe using awk, sed, perl....

Thanks a lot!

echo "${a#${a%?}}"

# OR
echo "${a}" | sed 's/.*\(.\)/\1/' 

# OR
echo "${a}"  | nawk '{print substr($0, length($0))}'

BTW - it's -2c as there's a trailing newline too.....

Cheers
