Why are utf8_encode & utf8_decode in the XML module?

Why are utf8_encode & utf8_decode NOT in the string module?

Because the actual low-level utf8_encode code is part of the expat
library that implements xml.  As of Apache-1.3.7 these functions are
built into Apache and you can compile PHP simply using --with-xml (as of
3.0.12) and you will have access to these functions.  Since the
functions are already in Apache you are not adding any extra code either
since the code is in there whether you use --with-xml or not.
