Problem with reading characters

Hello,
if I try this (in bash):
Code:
#!/bin/bash
cat leercaracter.sh | while read linea
do
   # read character by character
   echo $linea | while read -n 1 caracter
   do
      echo $caracter
   done
done

New lines, spaces, tabs aren't showed by echo.

How can I 'echo' those characters?

Thank you
