replace control character ascii into page


I observe that a copy-paste containing the control character ‘^L’ (ie FF) causes an error with ‘vimrepress’.

WordPress publishes the page but vimpress cannot load it. I would like to replace this ‘^L’ character with a space in one and, if possible, several pages either with “adminer”, or with a plugin, or from the editor.

Any ideas ?
