I think the change you made only ensures that the value cannot exceed
0x1fffff -- not 0x10ffff. You probably need to do something like this:
diff --git a/lib/libc/locale/utf8.c b/lib/libc/locale/utf8.c
index 55e2931..8ccfdb1 100644
--- a/lib/libc/locale/utf8.c

}
- if (wch >= 0xd800 && wch <= 0xdfff) {
+ if ((wch >= 0xd800 && wch <= 0xdfff) || wch > 0x10ffff) {
