Laravel 4 - 未显示文本字段的重音符号

I've got a problem on a laravel 4 project. My db, tables and fields are in utf8_unicode_ci. The problem appears only with text fields, it works well with varchar fields

The accents are not shown. It's not like it was an encoding problem with "é" instead of "é".

For exemple in the sentence : "Le soleil d'été éclate", i'll got "Le soleil d't clate".

Here's my code.

app/config/database.php

'driver'    => 'mysql',
...
'charset'   => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix'    => '',

In the view, i use a classic blade echo {{ $myobject->field }}

Any help would be greatly appreciated !

Thanks.

PS : Sorry for my english.
