How to get URL parameter via Joomla api with decoded strings?

Question

how can I get the full url parameter with the url-encoded values

?myParam=dummy%C3%B6%C3%A4%C3%BC

this is the decoded url:

?myParam=dummyöäü

if I use

$myText = urldecode(JFactory::getApplication()->input->get('myParam'));

the encoded or directly entered umlauts are missing in my var myText

Answer 1

Use string filter instead of the default cmd filter:

JFactory::getApplication()->input->get('myParam', '', 'string')

Or:

JFactory::getApplication()->input->getString('myParam')
