Filter "lower" destroys encoding strings

Hello, I use polish language, so i have chars: "ą", "ś", "ź", "ć" etc. If i used filter "lower", this chars die.

It's very sad for me. Thank you.


Check your system, PHP and Database to set charset UTF-8. Another way - create custom filter.


everywhere I have set UTF-8

You have to install the mbstring extension
