This seems to be already done in the case of 00A0 (NO-BREAK SPACE) which appears as an underscore with a distinctive face. It *looks* like I should be able to do this via the customization option "Whitespace Display Mappings", but no matter what I do, attempting to "Apply" the changes results in an error message, "This field should contain a single character". (This message occurs even if I try to change one of the display characters of an existing entry in the list and apply.) Feeling desperate, I copied the existing value of whitespace-display-mappings directly into my custom.el file, and manually added a new entry for A007 (8199) on the model of the existing entry for 00A0 (160), but this seems to have no effect on the display. (This is using Emacs 25, in case it should make a difference.) -- Will
