Thanks a lot for the kind words and for the pointer to the *Light-weight Bounds Checking* paper, which is definitely an interesting and highly related paper.

We’re happy to move this PR work forward, i.e., support wide-character functions such as `wcscpy()` for ASan. Would it be preferable to open a new PR rebased on main, or to try to revive this one directly?
