This has the benefit that if something goes wrong, you are able to either re-run the conversion or continue a conversion, while your old board is still accessible.

 	<p>Please note that this conversion process may take quite some time and depending on your hosting provider this may result in it failing (due to web server resource limits or other timeout issues). If this is the case, you should ask your provider if they are willing to allow the convert script to temporarily exceed their limits (be nice and they will probably be quite helpful). If your host is unwilling to increase the limits to run the convertor, please see this article for performing the conversion on your local machine: <a href="https://www.phpbb.com/kb/article/offline-conversions/">Knowledge Base - Offline Conversions</a></p>

 	<p><strong>http 500 / white pages</strong> The conversion is a load-heavy procedure. Restrictions imposed by some server hosting providers can cause problems. The most common causes are: values too low for the PHP settings <code>memory_limit</code> and <code>max_execution_time</code>. Limits on the allowed CPU time are also a frequent cause for such errors, as are limits on the number of database queries allowed. If you cannot change such settings, then contact your hosting provider or run the conversion procedure on a different computer. The phpBB.com forums are also an excellent location to ask for support.</p>

 <p>The <a href="http://en.wikipedia.org/wiki/Universal_Character_Set">Universal Character Set (UCS)</a> described in ISO/IEC 10646 consists of a large amount of characters. Each of them has a unique name and a code point which is an integer number. <a href="http://en.wikipedia.org/wiki/Unicode">Unicode</a> - which is an industry standard - complements the Universal Character Set with further information about the characters' properties and alternative character encodings. More information on Unicode can be found on the <a href="http://www.unicode.org/">Unicode Consortium's website</a>. One of the Unicode encodings is the <a href="http://en.wikipedia.org/wiki/UTF-8">8-bit Unicode Transformation Format (UTF-8)</a>. It encodes characters with up to four bytes aiming for maximum compatibility with the <a href="http://en.wikipedia.org/wiki/ASCII">American Standard Code for Information Interchange</a> which is a 7-bit encoding of a relatively small subset of the UCS.</p>
 
 <h4>phpBB's use of Unicode</h4>
-<p>Unfortunately PHP does not faciliate the use of Unicode prior to version 6. Most functions simply treat strings as sequences of bytes assuming that each character takes up exactly one byte. This behaviour still allows for storing UTF-8 encoded text in PHP strings but many operations on strings have unexpected results. To circumvent this problem we have created some alternative functions to PHP's native string operations which use code points instead of bytes. These functions can be found in <code>/includes/utf/utf_tools.php</code>. They are also covered in the <a href="http://area51.phpbb.com/docs/code/">phpBB3 Sourcecode Documentation</a>. A lot of native PHP functions still work with UTF-8 as long as you stick to certain restrictions. For example <code>explode</code> still works as long as the first and the last character of the delimiter string are ASCII characters.</p>

 <p>phpBB only uses the ASCII and the UTF-8 character encodings. Still all Strings are UTF-8 encoded because ASCII is a subset of UTF-8. The only exceptions to this rule are code sections which deal with external systems which use other encodings and character sets. Such external data should be converted to UTF-8 using the <code>utf8_recode()</code> function supplied with phpBB. It supports a variety of other character sets and encodings, a full list can be found below.</p>
