Hi Alvin, what I can confirm for sure is that a text length is not a buffer size, so the text length is exactly the size of the strings _without_ the null terminator. So the current behavior is the good one.
IMHO, If you saw a different behavior in 1.3 ; this was clearly a bug that is solved today apparently.
