443 | * Converts UTF-8 encoded string to UTF-16LE. | |
444 | * | |
445 | * To support repositories with legacy-encoded file names, invalid UTF-8 bytes | |
446 | * 0xa0 - 0xff are converted to corresponding printable Unicode chars \u00a0 - | |
447 | * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable | |
448 | * Unicode) are converted to hex-code. | |
449 | * | |
450 | * Lead-bytes not followed by an appropriate number of trail-bytes, over-long | |
451 | * encodings and 4-byte encodings > \u10ffff are detected as invalid UTF-8. | |
452 | * | |
453 | * Maximum space requirement for the target buffer is two wide chars per UTF-8 | |
454 | * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]). | |
455 | * | |
456 | * The maximum space is needed only if the entire input string consists of | |
457 | * invalid UTF-8 bytes in range 0x80-0x9f, as per the following table: | |
458 | * | |
459 | * | | UTF-8 | UTF-16 | | |
460 | * Code point | UTF-8 sequence | bytes | words | ratio | |

469 | * (a) encoded as UTF-16 surrogate pair | |

471 | * | |
472 | * Note that, while the UTF-8 encoding scheme can be extended to 5-byte, 6-byte | |
473 | * or even indefinite-byte sequences, the largest valid code point \u10ffff | |
474 | * encodes as only 4 UTF-8 bytes. | |
