* Fix TkUtfAtIndex(), still was not 100% correct.jan.nijtmans2020-05-201-1/+2
| | | Simplify TKNSString::DString, since Tcl_UniCharToUtf() is already capable of surrogate handling with a proper Tcl version.

| | | | | | | | | | | | events Tk doesn't know about. (cherry-pick): Protect better against possible confusion between XGenericEvent's and (Tcl-specific) XVirtualEvent's: If "name" == NULL, assume it's a XGenericEvent, so don't crash on that just ignore. Also don't use "virtual" as variable name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | name constness change. Although dkf's solution (simply adding a type cast) is correct as well, changing the return value (as das suggested) has the advantage that all Tk_OptionPrintProc implementations don't need a type cast any more in its code. This makes all those functions robust against the -Wwrite-strings warning option. Further on, the customPtr field of Tk_ConfigSpec can be a constant, without any danger of source incompatibility.
