THIS FUNCTION SHOULD BE USED IN ONLY VERY SPECIALIZED CIRCUMSTANCES.
+Instead, B<Almost all code should use L</uvchr_to_utf8> or
+L</uvchr_to_utf8_flags>>.
-It adds the UTF-8 representation of the Unicode code point C<uv> to the end
-of the string C<d>; C<d> should have at least C<UTF8_MAXBYTES+1> free
-bytes available. The return value is the pointer to the byte after the
-end of the new character. In other words,
-
- d = uvoffuni_to_utf8_flags(d, uv, flags);
-
-or, in most cases,
-
- d = uvoffuni_to_utf8_flags(d, uv, 0);

-where uv is a code point expressed in Latin-1 or above, not the platform's
-native character set. B<Almost all code should instead use L</uvchr_to_utf8>
-or L</uvchr_to_utf8_flags>>.
-
-This function will convert to UTF-8 (and not warn) even code points that aren't
-legal Unicode or are problematic, unless C<flags> contains one or more of the
-following flags:
-
-If C<uv> is a Unicode surrogate code point and UNICODE_WARN_SURROGATE is set,
-the function will raise a warning, provided UTF8 warnings are enabled. If instead
-UNICODE_DISALLOW_SURROGATE is set, the function will fail and return NULL.
-If both flags are set, the function will both warn and return NULL.
-
-The UNICODE_WARN_NONCHAR and UNICODE_DISALLOW_NONCHAR flags correspondingly
-affect how the function handles a Unicode non-character. And likewise, the
-UNICODE_WARN_SUPER and UNICODE_DISALLOW_SUPER flags, affect the handling of
-code points that are
-above the Unicode maximum of 0x10FFFF. Code points above 0x7FFF_FFFF (which are
-even less portable) can be warned and/or disallowed even if other above-Unicode
-code points are accepted, by the UNICODE_WARN_FE_FF and UNICODE_DISALLOW_FE_FF
-flags.
-
-And finally, the flag UNICODE_WARN_ILLEGAL_INTERCHANGE selects all four of the
-above WARN flags; and UNICODE_DISALLOW_ILLEGAL_INTERCHANGE selects all four
-DISALLOW flags.
+This function is like them, but the input is a strict Unicode
