utf8proc library, Unicode license

The Apache Lucy podling is considering bundling the utf8proc Unicode
processing library:

http://www.public-software-group.org/utf8proc

The Public Software Group generally releases under X11/MIT licensing (see
<http://www.public-software-group.org/licenses>), but utf8proc also includes
generated files under a license from the Unicode consortium – see Exhibit 1 at
this link:

http://www.unicode.org/copyright.html

The Unicode consortium's license was discussed in LEGAL-108, but that issue
was resolved without adding it to <http://www.apache.org/legal/resolved.html>.

Is it acceptable for an ASF product to include utf8proc as a bundled
dependency?
