Actually it is not easy since it is not exported. The basename is
exported but not the full name. I'll correct that soon.

This code is only used if USE_UNICODE is false, which means that the
perl used cannot run
 require Encode;
 require Unicode::Normalize;
In that case,
 sprintf("_%04x", $ccode);
should fail.

The code used with recent perl (more recent that 5.6 or the like) is 
in sub unicode_to_protected($) and is
  $result .= '_' . lc(sprintf("%04x",ord($1)));

Though your code is interesting because currently we don't handle right 
codepoints above 0xFFFF.

It is part of the ref to external manual specification we devised,
mostly with Karl. But this part  of the specification never got
implemented in makeinfo and so is only here as a proof of concept in 
texi2html. The reference is on a texinfo mailing list, I can find it if
you want to.

Now for the targets for cross-manual html xrefs when you don't split
according to the specification, there is a --node-files option for
texi2html which insures that there is a file which redirects to the
right place, with something like
  <meta http-equiv="Refresh" content="2; url=node-chap1.html#node-sec1">
and as text:
  <p>The node you are looking for is at <a 
href="node-chap1.html#node-sec1">node sec1</a>.</p>
