problems with ditto 1.02 modx 0.95 and utf-8

hello modx community
i have a little problem after upgrading from modx 0.92 to 0.95. if i choose the standart system settings "utf-8" encoding in the charset system settings (insteat of iso 8859-1) i get the following error message if i navigate to a site which uses ditto 1.02: Fatal error: Call to undefined function: utf8_encode() in /var/www/html/ewk/assets/snippets/ditto/ditto.class.inc.php on line 201
if i changes back to is08859-1 ditto works fine but all german "umlauts" in the manager are a bit mixed up. i´m no php man but i like modx very much (because of it´s easy using)
the general language is german, server is a linux server with apache and mysql 4.
ps. sorry for my bad english..

i forgott this the call of ditto in the template
[[Ditto? &tpl=`DittoTemplate` &summarize=`3`]]

and the chunk code
<div class="ditto_summaryPost">
<p>
<img src="assets/images/drehstern_blau_klein.gif" alt="stern" width="10" height="14" />&nbsp;
<a href="[~[+id+]~]">[+title+]</a>
[+summary+]
</p>
</div>

thank´s stephan

utf8_encode is built into PHP so I don’t see how that error is possible...

Can you post your server config?

thanks,
i don´t know if i post it for a second time.
i attached a html file (zip package) with the php / server config.
for my self i´m not very firm with php.
so i hope the config would be usefull: there is php 4.33 installed.

thanks stephan

the problem is solved there was a faillure in the server configuration,
thanks
stephan
