I don't know of any. (I'm assuming that you're talking about the calls from MySQL - http://www.java2s.com/Tutorial/MySQL/0460__String-Functions/0920__UNHEX.htm)

I suspect, but haven't tried, that they would be one or two-liners in Boost.Spirit.

You want something like this?
        template <typename InputIterator, typename OutputIterator>
        OutputIterator hex ( InputIterator first, InputIterator last, OutputIterator out );

        template <typename InputIterator, typename OutputIterator>
        OutputIterator unhex ( InputIterator first, InputIterator last, OutputIterator out );

[ + range based versions ]
[ + versions that work on char/wchar_t/short/int/long/long long, etc]
