These are the utilities that perform operations on char arrays representing Tcl string values. They are inherently limited to the arrays with length no greater than INT_MAX. They also are written for the Modified UTF-8 encoding expected of string values in Tcl 8. Any changes to those assumptions in Tcl 9 will require something new, either revisions to these routines, or development of new routines with broader capabilities while these persist as limited legacy support mechanisms.
