Replace all html special characters in Smarty

Question

I want to truncate a string in Smarty
This is the scenario:
The string is "Test!abc". Maximum characters allowed = 5.
Smarty gets string.
If I use {$string}, I get the desired result "Test!abc"
If I use {$string|truncate:5:"..":true} I get "Test&.."

How can I make truncate after html chars conversion. Prefer not to make it in php.
I know about "replace", but it will look like "|replace..|replace..|......"

Solution 1

You could try something like:

{$string|html_entity_decode:2:"UTF-8"|truncate:5:"...":true|htmlentities:2:"UTF-8"} 

Solution 2

If you're using Smarty 3.1 you can have a look at the unescape modifier.

{$string|unescape:"entity"|truncate:5}

Solution 3

In Smarty 2 you can try this one

{$string|html_entity_decode|truncate:5}
