This could be a bug in Perl or your not using the correct syntax to handle the variable.
Here is my fix to your code.
#!/usr/bin/perl
my $code1='my $var_with_é_accent;';
print "Eval buggy code\n";
eval {$code1;}; # Should see "Useless use of private variable in void
+context at Untitled line 6."
print "ERR = $@" if ($@);; # Error doesnt show here
print "DONE\n";
my $string;
my $code2='$string="new eval done";';
print "Eval good code\n";
eval $code2;
print "ERR = $@" if ($@);
print "string is : $string\n"; # This Works
print "DONE\n";
Good Luck ^^

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
