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

*
|
|
* Maximum space requirement for the target buffer is three UTF-8 chars per
|
|
* wide char ((_wcslen(wcs) * 3) + 1).
|
|
*
|
|
* The maximum space is needed only if the entire input string consists of
|
|
* UTF-16 words in range 0x0800-0xd7ff or 0xe000-0xffff (i.e. \u0800-\uffff
|
|
* modulo surrogate pairs), as per the following table:
|
|
*
|
|
* | | UTF-16 | UTF-8 |
|
|
* Code point | UTF-16 sequence | words | bytes | ratio
|
|
* --------------+-----------------------+--------+-------+-------
|
|
* 000000-00007f | 0000-007f | 1 | 1 | 1
|
|
* 000080-0007ff | 0080-07ff | 1 | 2 | 2
|
|
* 000800-00ffff | 0800-d7ff / e000-ffff | 1 | 3 | 3
|
|
* 010000-10ffff | d800-dbff + dc00-dfff | 2 | 4 | 2
|
|
*
|
|
* Note that invalid code points > 10ffff cannot be represented in UTF-16.
|
|
*
|
|
* Parameters:
|
|
* utf: target buffer
|
|
* wcs: wide string to convert
|
|
* utflen: size of target buffer
|
|
*
|
|
* Returns:
|
|
* length of converted string, or -1 on failure
|
|
*
|
|
* Errors:
|
|
* EINVAL: one of the input parameters is invalid (e.g. NULL)
|
|
* ERANGE: the output buffer is too small
