Non-printing, zero-width characters (specifically the Unicode U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK characters) are inserted into the text. These are invisible, although some editors/applications may purge them. In the case of Prepend every word, only the LTR mark is used before each word. In the case of Replace all spaces, the spaces are replaced with Unicode U+2005 FOUR-PER-EM SPACE.
