so I kinda assume that Perl will handle with this kind of stuff for me.
Having Perl remove the BOM automatically would be bad. print while <$fh>; would no longer print out a file exactly, for example. It wouldn't be possible to print out a file exactly by other means either.
However, if file contains that BOM, my program does not understand the first line in the file
Patient: "Doctor, it hurts when I do this."
Doctor: "So don't do it!"
If your program doesn't accept BOMs, don't feed it any. BOMs are not required.
Alternatively, you could change your spec and your program to accept it.
while (<$fh>) {
s/\x{FEFF}//g;
...
}

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).
