Is it possible to change how a character is displayed?
I explain better, I want to replace the character '*' with math unicode '∗' [U+2217]. This should affect only the way the character is displayed not the file content.
Note: I have already tried to use the conceal feature, however I am not really satisfied by the result.
I would like to have a behaviour similar to listchars and list for example listchars=space:.
