I spent most of last week wading/stumbling through a conversion of a large part of my system to UTF-8. After much reading and inexplicableness, I'm virtually there. Still have one problem though; one routine expects UTF-8 data and can crash if it gets some from a non-UTF-8 file. So I need to test a file for UTF-8-edness. I have read much documentation/Perlmonks/Stackoverflow and apparently the following should work:
open (ORDERFILE, '<:encoding(UTF-8)', $emailfile) or return (@err, "Co
+uld not open order email file: $emailfile");
my(@LINES) = <ORDERFILE>;
my $filedata = <ORDERFILE>;
close(ORDERFILE);
use Encode;
eval { my $utf8 = decode("utf8", $filedata, Encode::FB_CROAK ) };
return(@err, "File was not encoded in UTF-8") if ($@);
But I have ANSII files for which this doesn't return but just outputs lots of warnings such as: utf8 "\xA3" does not map to Unicode. If I remove the '<:encoding(UTF-8)', argument from 'open', it still works but there are no warnings. A salient insight would be a welcome relief if there are any ideas?

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).
