Use of Unicode middle dot in fragment

Folks,
 
We wanted to use a Unicode "middle dot" (#x00B7) in a fragment (e.g.
http://www.xyz-corp/XP736#PHO-482303·3715A ) but some RDF or OWL software
seems to have problems with that.
 
Can anyone give me a suggestion what exotic character I can use safely
instead? It needs to be exotic, so that no one will use it for the fragment,
and so that a parser can easily recognize the last part (here: 3715A).
 
Regards,
Hans
