Umlaut problem when integrate Katalon with Jenkins

I have this problem when integrate Katalon with Jenkins.

I have an assertion based on comparing 2 strings. Actual value with expected.

'Wirkstoffe muessen über" this is the string that I need to check.

I get this error:
Expected element property value ‘Wirkstoffe m�ssen �ber Apothekensoftware ermittelt werden’ is not equal with actual property value ‘Wirkstoffe müssen über Apothekensoftware ermittelt werden’, Seems that umlauts are not correctly interpreted.

Running locally, everything is ok. Any ideea? Is a Jenkins issue?
