wordWrapper use chunk_split. which will break multi-byte charset in the middle.
As a result, the db_layout.php of page will show many broken character

It should use wordwrap in CSS. But seem not supported by Firefox.

my edition of it rewrite the logic.
And it assert all incoming character are UTF-8.
(someone please change it to fix)

--- CVS 1.28.2.2 ---
function wordWrapper($content,$max=50,$char=' ') {
$array = split(' |'.chr(10),$content);
foreach($array as $val) {
if (strlen($val)>$max) {
$content=str_replace($val,substr(chunk_split($val,$max,$char),0,-1),$content);
}
}
return $content;
}
-- my edition ---
function wordWrapper($content,$max=50,$char=' ') {
$segments=preg_split("/[\\b\r\n ]/",$content,-1,PREG_SPLIT_DELIM_CAPTURE);
$csConv=$GLOBALS['LANG']>csConvObj;
foreach($segments as &$segment){
if(strlen($segment)>$max){ // quick check when it is really short
$s=$segment;
$segment='';
while($csConv->strlen('utf-8',$s)>$max){
// It should do better for wide character.
// but csConvObj do not provide that information,
// and browser can do wrap between wide characters
$segment.=$csConv->substr('utf-8',$s,0,$max);
$segment.="\r\n";
$s=$csConv->substr($s,$max);
}
$segment.=$s;
}
}
return implode('',$segments);
}
