Replace special characters (german umlauts)

Question

I need to replace special characters in Magento.

For example:

<?php echo $string; //echoes "ausführung"?>
  <?php if (strpos($string,"ü")!==false) 
    {echo "umlaut"}?>

My problem is that the if-statement is never true. I also tried to html_entity_decode or something, without a result.

Does anyone know how to replace special characters there? I need to use the string as a CSS class name and special characters are not allowed there.

Take a look at Mage_Core_Helper_Data::removeAccents($string, $german=false).

This should exactly do what you want, but unfourtunatly there is a bug ...

Setting $german to true doesn't work. If you want to use this, please check this: https://github.com/OpenMage/magento-lts/pull/345 and fix this "somehow" (I know ... do not touch core files :P)

Use str_replace() instead

It replaces your character if found
