Describe the bug

caml_utf8_of_utf16(String.fromCharCode(0xdbff, 0xdfff)) generate wrong utf8 encoding string

line 107 should be c > 0xdbff since 0xdbff is a valid surrogate

Expected behavior

expected result: b'\xf4\x8f\xbf\xbf' (get from python bytes.fromhex('dbffdfff').decode('utf-16be').encode('utf-8'))

actual result: ef bf bd ed bf bf, get from

Array.from(caml_utf8_of_utf16(String.fromCharCode(0xdbff, 0xdfff)))
    .map((c) => c.charCodeAt(0).toString(16).padStart(2, "0"))
    .join(" ")
