+    WTF-8. If `utf16` is NUL terminated, `utf16_len` can be set to -1,

+
+    Convert UTF-16 (or UCS-2) data in `utf16` to WTF-8 data in `*wtf8_ptr`. The
+    `utf16_len` count (in characters) gives the length of `utf16`. If `utf16`
+    is NUL terminated, `utf16_len` can be set to -1, otherwise it must be
+    specified. If `wtf8_ptr` is `NULL`, no result will be computed, but the
+    length (equal to `uv_utf16_length_as_wtf8`) will be stored in `wtf8_ptr`.
+    If `*wtf8_ptr` is `NULL`, space for the conversion will be allocated and
+    returned in `wtf8_ptr` and the length will be returned in `wtf8_len_ptr`.
+    Otherwise, the length of `*wtf8_ptr` must be passed in `wtf8_len_ptr`. The
+    `wtf8_ptr` must contain an extra space for an extra NUL after the result.
+    If the result is truncated, `UV_ENOBUFS` will be returned and
+    `wtf8_len_ptr` will be the length of the required `wtf8_ptr` to contain the
+    whole result.
