Re: [BUG] 'non-empty string' >? '' returns false on amd64 arch

I confirm the problem. Looks like there's a bug in UTF-8 handling in
function mb_strnicmp() in mbyte.c, specifically in the following "if"
which was introduced by patch 7.3.040:

/* Don't case-fold illegal bytes or truncated characters. */
if (utf_ptr2len(s1 + i) < l || utf_ptr2len(s2 + i) < l)
return -1;

The check "utf_ptr2len(s2 + i) < l" is wrong.
