IIRC character_limiter() doesn't echo results, just returns them. So:

IIRC character_limiter（）不回显结果，只返回它们。所以：

1) make sure you've loaded the text helper in your controller before calling that function
2) try with:

1）确保在调用该函数之前已在控制器中加载了文本助手2）尝试使用：

<description><?php echo htmlspecialchars(character_limiter($entry->text_nw, 200)); ?></description>
