variable. Remember though, that hash keys in perl are free to contain
embedded nulls, so using C<strlen()> or similar is not a good way to find
the length of hash keys. This is very similar to the C<SvPV()> macro
-described elsewhere in this document.
+described elsewhere in this document. See also C<HeUTF8>.
+
+If you are using C<HePV> to get values to pass to C<newSVpvn()> to create a
+new SV, you should consider using C<newSVhek(HeKEY_hek(he))> as it is more
+efficient.

+=for apidoc Am|char*|HeUTF8|HE* he|STRLEN len
+Returns whether the C<char *> value returned by C<HePV> is encoded in UTF-8,
+doing any necessary dereferencing of possibly C<SV*> keys. The value returned
+will be 0 or non-0, not necessarily 1 (or even a value with any low bits set),
+so B<do not> blindly assign this to a C<bool> variable, as C<bool> may be a
+typedef for C<char>.

Returns the key as an C<SV*>, or C<NULL> if the hash entry does not
