And if so -- what? My uni-confusables package in the GNU ELPA would help detect things like б (CYRILLIC SMALL LETTER BE) confused with the number 6. The relevant line from confusables.txt is: 0431 ; 0036 ; SL # ( б → 6 ) CYRILLIC SMALL LETTER BE → DIGIT SIX # which maps to (1073 "6") in `uni-confusables-char-table-single'. EWW and SHR could opportunistically use that table to highlight such characters. I could also add RTL markers and other useful things to uni-confusables if you think it's the right place, and maybe provide the function for EWW and SHR and others to use when looking for suspicious characters. Or I could keep the package to a single purpose. I'm not sure of the right thing because this feels a little bit like core functionality. Ted
