I don't think you can have different terminfo entries for different character sets for the same terminal type, i.e. you'd need to create charset-specifc types such as "xterm-cp850". > I've added > > csin=\233, > > but I'm not sure if it's really necessary, and if it's wrong when I switch > the Character Set. tgetstr() returns the value defined in xterm-terminfo, > which may be wrong for another character set.

Looking at the standard, 'csin' isn't meant for a keycode, but for a command sent to the terminal, namely for the "Init sequence for multiple codesets". I'm afraid I don't know what that means though, nor why the xterm terminfo for it is empty. > I'm not sure if this can be solved inside mintty, is > there a fallback if an entry in terminfo is missing? There isn't a fallback in the terminfo system itself, so I guess that's up to each terminfo-using program (or its configuration).
