Home page dashboard boxs not loaded

[addady2]

I found the cause of the problem

The function json_encode in modules/Home/HomeWidgetBlockList.php fail

PHP Code:

echo json_encode($widgetHTML); 


json_last_error() returns Malformed UTF-8 characters, possibly incorrectly encoded

In my case $widgetHTML contain non Latin charters.

Some lines in $widgetHTML (like filter name in key metric box) are truncate.
... (3 dots) added to the filter names, probably because of global parameter like: Application_ListView_Max_Text_Length.

Look like the truncation is not UTF8 safe and break the string encoding.
