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

+ * \u00ff, and invalid UTF-8 bytes 0x80 - 0x9f (which would make non-printable

+ *
+ * Lead-bytes not followed by an appropriate number of trail-bytes, over-long

+ *
+ * Maximum space requirement for the target buffer is two wide chars per UTF-8
+ * char (((strlen(utf) * 2) + 1) [* sizeof(wchar_t)]).
+ *
+ * The maximum space is needed only if the entire input string consists of
