8f557b84f6 was done because `text` is sometimes just an int,
but the fix was only applies to the padding calculation.
Unfortunately, the padding direction is also different between strings
and integers, which means the behaviour is now incoherent.
Let's convert `text` to a string before we start doing anything so that
everything afterwards is coherent.
