/usr/include/unicode/ucnv.h belongs to dev-libs/icu. It looks like
dev-libs/libxml2 needs it even if it is installed with USE="-icu". Could
you report the bug on <https://bugs.gentoo.org/>?

As a workaround, re-install dev-libs/libxml2 with USE="icu".

Kind regards, tastytea

Was your dev-libs/libxml2 built with USE=icu? And is icu installed? If
you look in /usr/include/libxml2/libxml/encoding.h you probably see,

  #ifdef LIBXML_ICU_ENABLED
  #include <unicode/ucnv.h>
  #endif

so that unicode header should only be used when libxml2 was built with
USE=icu. In that case, USE=icu also pulls in dev-libs/icu, which is
what provides the header.

Thanks for the suggestion.
I installed: dev-libs/icu (as it was missing).
This will creates the ucnv.h file that is missing.
