Dunno, that wasn't my benchmark.  It makes the web server go faster
(e.g. guile examples/web/debug-sxml.scm).

The reason it makes sense to optimize for this encoding is because it's
our narrow encoding.  If we switch to utf-8 internally (for example),
this path doesn't make sense any more.

:)  Will fix.
