25/*
26 * Lenient UTF-8 differs from conformant UTF-8 in that it allows surrogate
27 * code points with their "natural" encoding.
28 * Effectively, this allows a mix of UTF-8 and CESU-8 as well as encodings of
29 * single surrogates.
30 *
31 * This is not conformant with UTF-8.
32 *
33 * Supplementary code points may be encoded as pairs of 3-byte sequences, but
34 * the macros below do not attempt to assemble such pairs.
