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