423 * Converts UTF-8 encoded string to UTF-16LE.

425 * To support repositories with legacy-encoded file names, invalid UTF-8 bytes
426 * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 -
427 * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable
428 * Unicode) are converted to hex-code.
429 *
430 * Lead-bytes not followed by an appropriate number of trail-bytes, over-long
431 * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8.
432 *
433 * Maximum space requirement for the target buffer is two wide chars per UTF-8
434 * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
435 *
436 * The maximum space is needed only if the entire input string consists of
437 * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table:
438 *
439 * | | UTF-8 | UTF-16 |
440 * Code point | UTF-8 sequence | bytes | words | ratio
441 * --------------+-------------------+-------+--------+-------

443 * 000080-0007ff | c2-df + 80-bf | 2 | 1 | 0.5
444 * 000800-00ffff | e0-ef + 2 * 80-bf | 3 | 1 | 0.33
445 * 010000-10ffff | f0-f4 + 3 * 80-bf | 4 | 2 (a) | 0.5

447 * invalid | a0-ff | 1 | 1 | 1
448 *
449 * (a) encoded as UTF-16 surrogate pair
450 * (b) encoded as two hex digits
451 *
452 * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte
453 * or even indefinite-byte sequences, the largest valid code point \u10ffff
454 * encodes as only 4 UTF-8 bytes.
455 *
456 * Parameters:

458 * utf: string to convert
459 * wcslen: size of target buffer (in wchar_t's)
