There is however an easy solution: use the modifier 'u'. [1] It can
reduce performance, but at least you have a UTF-8 aware regular expression.

And now tested with vge_tagcloud and it works fine.
Alex, however you won't be able to make this change in TypoScript,
because of the way it's interpreted for now. You'll need to hack the
code of the "pi1" plugin yourself. Edit class.tx_vgetagcloud_pi1.php, go
to line 408:
$rawKeywords = preg_split('/' . addcslashes($this->conf['splitWords'],
"'/") . '/', strip_tags($row[$aField]));
and change it too:
$rawKeywords = preg_split('/' . addcslashes($this->conf['splitWords'],
"'/") . '/u', strip_tags($row[$aField]));
The only difference is the "u" added after the last slash.
The usage of the "splitWords" property needs to be changed to include
the regexp delimiters so that people can enter modifiers too. I hadn't
thought about that originally. I'll use your bug report to cover this issue.
Cheers
