423 * To support repositories with legacy-encoded file names, invalid UTF-8 bytes
424 * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 -
425 * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable
426 * Unicode) are converted to hex-code.
427 *
428 * Lead-bytes not followed by an appropriate number of trail-bytes, over-long
429 * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8.
430 *
431 * Maximum space requirement for the target buffer is two wide chars per UTF-8
432 * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
433 *
434 * The maximum space is needed only if the entire input string consists of
435 * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table:
436 *
437 * | | UTF-8 | UTF-16 |

439 * --------------+-------------------+-------+--------+-------

446 *
447 * (a) encoded as UTF-16 surrogate pair
448 * (b) encoded as two hex digits

450 * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte
451 * or even indefinite-byte sequences, the largest valid code point \u10ffff

453 *
454 * Parameters:
