385 * Converts UTF-8 encoded string to UTF-16LE.
386 *
387 * To support repositories with legacy-encoded file names, invalid UTF-8 bytes
388 * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 -
389 * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable
390 * Unicode) are converted to hex-code.
391 *
392 * Lead-bytes not followed by an appropriate number of trail-bytes, over-long
393 * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8.
394 *
395 * Maximum space requirement for the target buffer is two wide chars per UTF-8
396 * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
397 *
398 * The maximum space is needed only if the entire input string consists of
399 * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table:
400 *
401 * | | UTF-8 | UTF-16 |
402 * Code point | UTF-8 sequence | bytes | words | ratio
403 * --------------+-------------------+-------+--------+-------
404 * 000000-00007f | 0-7f | 1 | 1 | 1
405 * 000080-0007ff | c2-df + 80-bf | 2 | 1 | 0.5
406 * 000800-00ffff | e0-ef + 2 * 80-bf | 3 | 1 | 0.33
407 * 010000-10ffff | f0-f4 + 3 * 80-bf | 4 | 2 (a) | 0.5

409 * invalid | a0-ff | 1 | 1 | 1
410 *
411 * (a) encoded as UTF-16 surrogate pair
412 * (b) encoded as two hex digits
413 *
414 * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte
415 * or even indefinite-byte sequences, the largest valid code point \u10ffff
416 * encodes as only 4 UTF-8 bytes.
417 *
418 * Parameters:
419 * wcs: wide char target buffer
420 * utf: string to convert
421 * wcslen: size of target buffer (in wchar_t's)
422 * utflen: size of string to convert, or -1 if 0-terminated
