-embed.pl, specifically a listing of functions, macros, flags, and variables
+F<embed.pl>, specifically a listing of functions, macros, flags, and variables
that may be used by extension writers. L<At the end|/Undocumented functions>
is a list of functions which have yet to be documented. The interfaces of
those are subject to change without notice. Any functions not listed here are
the UTF- encodings, and a string encoded in UTF-EBCDIC may occupy more bytes
than in UTF-8.
-Also, on some EBCDIC machines, functions that are documented as operating on
-US-ASCII (or Basic Latin in Unicode terminology) may in fact operate on all
-256 characters in the EBCDIC range, not just the subset corresponding to
-US-ASCII.
