At least in your second example, you are not properly decoding your input.
eval { $sCodepoints = decode( "iso-8859-1", $sLine, Encode::FB_CROAK )
+ };
if ( $@ )
{ # input was not iso-8859-1
print "> No ISO-8859-1, maybe UTF8 ?\n";
$sCodepoints = $sLine;
}
Here, $sCodepoints does not contain properly decoded UTF-8.
I would try a loop over the possible encodings:
for my $encoding_candidate (qw(iso-8859-1 UTF-8)) {
eval { $sCodepoints = decode( $encoding_candidate, $sLine, Encode::FB_
+CROAK ) };
if ( $@ )
{ # input was not $encoding_candidate
print "> Not $encoding_candidate\n";
#$sCodepoints = $sLine;
}
}

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).
