Why is toybox ls escaping by default here but not on Linux? Hmmm, it's gotta be
this call in crunch_qb():
// scrute the inscrutable, eff the ineffable, print the unprintable
else if ((len = wcrtomb(buf, wc, 0) ) == -1) len = 1;
Once again, I wist for stable/portable unicode functions in lib/unicode.c. I
know why I haven't GOT them (mostly), but this is just ridiculous. (They don't
have to be GREAT, but NOT THAT...)
(There's only 100k code points and MOSTLY I'm doing tests that return ONE BIT
answers. I'm aware it's a trap, but DUDE...)
Anyway, STILL not the actual issue at hand, the issue is that:
cfarm104 (homebrew):toybox landley$ generated/testdir/find
generated/testdir/testdir -iname aaaaaⱥⱥⱥⱥⱥⱥⱥⱥⱥ
generated/testdir/testdir/aaaaaⱥⱥⱥⱥⱥⱥⱥⱥⱥ
cfarm104 (homebrew):toybox landley$ generated/testdir/find
generated/testdir/testdir -iname aaaaaȺȺȺȺȺȺȺȺȺ
cfarm104 (homebrew):toybox landley$
The upper case string is not converting into the lower case string. Ok, let's
stick a +dprintf(2, "%d->%d\n", c, towlower(c)); into strlower() and it says
"570->58" which... is a colon? Hmmm, prepending LC_ALL=en_US.UTF-8 did not
change that.
It looks like macos towlower() refuses to return expanding unicode characters.
Possibly to avoid exactly the kind of bug this fixed, in exchange for corrupting
the data.
I don't know how to fix this other than stubbing out the test on macos, or
adding lib/unicode.c. (I _really_ want to find an 80/20 there. I'm aware I have
failed at least three previous attempts, and am 2/3 of the way to clearing off
my laptop so I can install the new OS version and put the big ram sticks back so
NOW IS NOT THE TIME, but still...)
