Hi Internals, I have opened a Pull Request to add|\f| (form feed) to the list of characters stripped by default in|trim()|,|ltrim()|, and|rtrim()|. Currently, the default behavior of|trim()| strips the following characters:|\n|,|\r|,|\t|,|\v|,|\0|, and space. The form feed character| \f| is notably missing, despite being widely recognized as a whitespace character (in python, rust...).

Also in PHP, where ctype_space() recognises \f as whitespace as well as all of those that trim() removes. (As the name implies, of course, this is because \f is recognised as whitespace in C.)
