TYPO3 Core

A test Typoscript

prefix = tx_form
confirmation = 1
postProcessor {
    1 = mail
    1 {
        recipientEmail = 
        senderEmail = 
    }
}
10 = TEXTLINE
10 {
    name = 2
    type = text
    filters {
        1 = trim
        1 {
            characterList = 05t
        }
    }
    label {
        value = TrimTest
    }
}

If you write "test50" into the textfield and submit the form you should see "es" on the confirmation page.
