... just get "\000\005issueentrust.net" translated to "0,5,issueentrust.net" ...
Try:
c:\@Work\Perl\monks>perl -wMstrict -le
"my $s = qq{\000\005issueentrust.net};
$s =~ s{ \A (.) (.) }{ sprintf '%d,%d,', ord($1), ord($2) }xmse;
print qq{'$s'};
"
'0,5,issueentrust.net'
Update 1: But this sounds like an XY Problem; it that really all you want?
Update 2: Here's an unpack approach:
c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le
"my $s = qq{\000\005issueentrust.net};
my ($flag, $tag, $issuer) = unpack 'C C/a a*', $s;
dd $flag, $tag, $issuer;
my $t = sprintf '%-6s %s %s', $flag, $tag, $issuer;
print qq{'$t'};
"
(0, "issue", "entrust.net")
'0 issue entrust.net'
(Update: Changed $remainder to $issuer in this code example because this naming corresponds better to terminology used in the OP.)

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).
