Digest #148 2021-05-02
I have been updating my XC-WIDTH function and need to understand what the width should be for control characters ( 1 to $1F and $80 to $9F ). Markus Kuhn's original wcwidth returns -1 for them. I have seen that Julia language returns 0. The function above returns 1. My suggestion would be to return 0. This question also applies to X-WIDTH. I could provide an updated and more complete function than the above
COMPARE compares characters, not cells. The maximum number of characters compared is specified by the u1 and u2 arguments.
