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

394 * To support repositories with legacy-encoded file names, invalid UTF-8 bytes
395 * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 -
396 * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable
397 * Unicode) are converted to hex-code.
398 *
399 * Lead-bytes not followed by an appropriate number of trail-bytes, over-long
400 * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8.
401 *
402 * Maximum space requirement for the target buffer is two wide chars per UTF-8
403 * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
404 *
405 * The maximum space is needed only if the entire input string consists of
406 * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table:
407 *
408 * | | UTF-8 | UTF-16 |
409 * Code point | UTF-8 sequence | bytes | words | ratio
410 * --------------+-------------------+-------+--------+-------

413 * 000800-00ffff | e0-ef + 2 * 80-bf | 3 | 1 | 0.33
414 * 010000-10ffff | f0-f4 + 3 * 80-bf | 4 | 2 (a) | 0.5

416 * invalid | a0-ff | 1 | 1 | 1
417 *
418 * (a) encoded as UTF-16 surrogate pair
419 * (b) encoded as two hex digits
420 *
421 * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte
422 * or even indefinite-byte sequences, the largest valid code point \u10ffff
423 * encodes as only 4 UTF-8 bytes.
424 *
425 * Parameters:

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