Hi Carol,
Fortuitously, some information about breadcrumbs came my way.
It appears that " > " may be most familiar as a delimiter.
In Angela Coulter's survey in 2002, of the sites the use breadcrumbs,
" > " was used almost half the time.
The next most popular delimiters were down near 10%.
" >> " was used on around 7% of the sites.
So " >> " is pretty (personal opinion about a sequence of two printable characters), but people who see breadcrumbs are mightly likely to be familiar with " > ".
More on breadcrumbs below.
Best wishes,
Bruce

Subject: Jakob Nielsen on breadcrumbs
As of 2003, Jakob Nielsen recommends ">" to separate levels in a breadcrumb
list.
http://www.useit.com/alertbox/991114.html
As of 2002, Angela Coulter et al
(http://www.angelacolter.com/site/breadcrumbs/) found that ">" was used on
47% of surveyed sites (see next sentence) that do use breadcrumbs. Only 17%
of the commercial sites in the original Google Catalog beta (predecessor to
froogle) used breadcrumbs. Location-based breadcrumbs were the most common.
Path-based breadcrumbs and attribute-based breadcrumbs were much less common.
Breadcrumbs were most effective right below the page title. In a small
sample of observed users at sites that used breadcrumbs, 93% of users
clicked on a breadcrumb at least once during a 15-task session requiring
navigation to complete each task. More than 50% used breadcrumbs on
multiple sites in the session. Users tended to trade off between the Back
button and the breadcrumbs, trying to judge which would more reliably get
them to where they wanted to be.
