Also in PHP, where ctype_space() recognises \f as whitespace as well as

By the way, I do not think NUL(\x00) should be trimed… In other languages (at least python and rust and libc) NUL is not a whitespace. I therefore opine NUL should be removed from trim in the future, but that is another issue.
I think the BC break would effect some users (every BC break does, but this one could annoy someone expecting \f not to be trim for years using php). I am on the fence about the break too, but I think the change do seems great to me according to other languages’ behaviours. I initially thought this is a bug when I discover this.
