PS 1.7 Remove last 13 chars from product title

[mycloudcms]

Hi, I need to hide the last 13 chars from product titles. It should be done within .tpl via smarty... but don't know how! I am using Prestashop 1.7

Thank you

Forget it! Future versions of 1.7 will completely do without Smarty

However, try this:  {$yourvariable|substr:-13}
