[rocco carbone]

Package: dash
Version: 0.5.4-8ubuntu1
Severity: minor

The following shell script reproduce the problem:

#
#!/bin/dash

var="This is bad '\0'"
echo "$var"

var="This is bad again '\0'nothing appears after the misterious terminator"
echo "$var"

############

this is the output produced on a system running Ubuntu 8.04.1
with dash 0.5.4-8ubuntu1

chumby:~> /bin/dash dash-bug.sh
This is bad '
This is bad again '

while the expected result should be:

This is bad '\0'
This is bad again '\0'nothing appears after the misterious terminator

as when the script is executed by the bash or other shells
