<p><b>2.</b> <span class='question'>I get the following error when I try to generate a PDF: Some data has already been output, can't send PDF file</span></p>
You must send nothing to the browser except the PDF itself: no HTML, no space, no carriage return. A common
case is having extra blank at the end of an included script file.<br>
If you can't figure out where the problem comes from, this other message appearing just before will help you:<br>
<br>
<b>Warning:</b> Cannot modify header information - headers already sent by (output started at script.php:X)<br>
The message may be followed by this indication:<br>
<br>
It means that script.php outputs something at line X. Go to that line and fix it.
In case the message doesn't show, check if PHP warnings are enabled. If they are not, enable them. If they are,
try adding this at the very beginning of your script:
(output started at script.php:X)<br>
<br>
which gives you exactly the script and line number responsible for the output. If you don't see it,
try adding this line at the very beginning of your script:
<div class="doc-source">
<pre><code>ob_end_clean();</code></pre>
</div>
</li>

<p><b>3.</b> <span class='question'>Accented letters are replaced with some strange characters like é.</span></p>
Don't use UTF-8 with the standard fonts; they expect text encoded in ISO-8859-1 or windows-1252.
You can use utf8_decode() to perform a conversion to ISO-8859-1:
Don't use UTF-8 with the standard fonts; they expect text encoded in windows-1252.
You can perform a conversion with iconv:
<div class="doc-source">
<pre><code>$str = utf8_decode($str);</code></pre>
<pre><code>$str = iconv('UTF-8', 'windows-1252', $str);</code></pre>
</div>
But some characters such as Euro won't be translated correctly. If the iconv extension is available, the
right way to do it is the following:
Or with mbstring:
<div class="doc-source">
<pre><code>$str = iconv('UTF-8', 'windows-1252', $str);</code></pre>
<pre><code>$str = mb_convert_encoding($str, 'windows-1252', 'UTF-8');</code></pre>
</div>
In case you need characters outside windows-1252, take a look at tutorial #7 or
