I spoke too soon. The special chart type for the maps apparently
accepts URI -encoded unicode chars, but NOT the regular chart API. If
we try, for example, to use the value %e2%99%86 (Neptune) as the
symbol to be plotted, the entire annotation list is not displayed at
all. Only the main data set
The Chart API expects URL-encoded UTF-8 characters. See the examples
at http://groups.google.com/group/google-chart-api/web/chart-types-for-map-pins
Here's a site that I've used in the past to obtain utf-8 hex values:

Good luck,

// I have not tested it, but I presume that chart legends will be
similarly affected.
var chart = ''; // Will hold entire chart definition to send to
Google.
var s = new Array(); var i=0; // Array with text samples to test.
