Title: More robust solution for unused control characters

This is a better fix for #6682 - all control characters are now set to be ignored in the escape_defaults keymap. I had previously missed a few (e.g., `^]`, `^-`, `^\`) in both the search and default keymaps. This should fully prevent control characters from getting inserted by typing at the REPL (although they can still get inserted via paste).
