Now I see a difference between "not compiled in" (declare(encoding) is ignored) and "not enabled" (declare(encoding) throws a warning). > For the question about why its not enabled by default?

That is, what the warning should tell me? [1] Sidenote: Maybe it could ignore declare(encoding='ASCII') ;) > > -- > regards, > > Kalle Sommer Nielsen > ka...@php.net > At all I think now, that the warning is probably the better reaction than just doing nothing. No further question, thanks for that :) Regards, Sebastian
