There are several solutions to this, but replacing the “arrows” with the more ubiquitous lt and gt is a quick fix.
This issue shows up for me in Chrome – mac ver 16.0.912.63
I understand it also shows up in older versions of IE.
You can find the code for “prev” and “next” arrows in the js folder of the ajax event calendar in the file is jquery.init_show_calendar.js, lines 137 and 138.
(particularly & #9668;)
Here’s the offender:
prev: ‘?’, // left triangle
next: ‘??‘ // right triangle
Replace those with
prev: ‘?<?‘, // left arrow
next: ‘?>?‘ //right arrow
Hope that helps.
(sorry, my & #9668; and & lt; is getting interpreted by the browser — I put a space in so it would render as code and not the glyph. The general idea is replace #9668 with lt)
