426 * To support repositories with legacy-encoded file names, invalid UTF-8 bytes
427 * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 -
428 * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable
429 * Unicode) are converted to hex-code.
430 *
431 * Lead-bytes not followed by an appropriate number of trail-bytes, over-long
432 * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8.
433 *
434 * Maximum space requirement for the target buffer is two wide chars per UTF-8
435 * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
436 *
437 * The maximum space is needed only if the entire input string consists of
438 * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table:
439 *
440 * | | UTF-8 | UTF-16 |
441 * Code point | UTF-8 sequence | bytes | words | ratio
442 * --------------+-------------------+-------+--------+-------

449 *
450 * (a) encoded as UTF-16 surrogate pair
451 * (b) encoded as two hex digits

453 * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte
454 * or even indefinite-byte sequences, the largest valid code point \u10ffff
455 * encodes as only 4 UTF-8 bytes.
456 *
457 * Parameters:

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