Ahhh, that makes sense.

You're right. Still these functions should be extend-/changeable, so
maybe making a global object $DIV, instantiated by
t3lib_div::makeInstance('t3lib_div'); would be a solution. That way you
could actually modify even the makeInstance function.

The problem is that the function is called from other scripts, which I
have no intention of changing. In particular I'm trying to solve the
problem for the da_newsletter extension, and I could fix at a higher
level, just figured it would be cleaner to do it in the div-script,
since the other encoding is done here.

Thanks a lot Ingmar, you saved me a lot of time there.
