Version 0.2.2 of package Markchars has just been released in GNU ELPA. You can now find it in M-x list-packages RET.
Markchars describes itself as: ========================================== Mark chars fitting certain characteristics ========================================== More at https://elpa.gnu.org/packages/markchars.html ## Summary: Mark special chars, by default nonascii, non-IDN chars, in modes where they may be confused with regular chars. See `markchars-mode' and `markchars-what'. There are two modes: confusable detection (where we look for mixed scripts within a word, without using the https://www.unicode.org/reports/tr39/ confusable tables) and pattern detection (where any regular expressions can be matched). The marked text will have the 'markchars property set to either 'confusable or 'pattern and the face set to either `markchars-face-confusable' or `markchars-face-pattern' respectively. ## Recent NEWS: [Not provided 🙁]
