In some sites, including Google Plus, when I press the comma in the text input it displays strange characters instead of putting in the comma. This only happens in Chrome. I tried it in IE and Firefox. I think it has something to do with the fact that the site appears to use a div with javascript instead of using an actual textbox.
I am not sure what is going on. It looks like some kind of debugging symbols or something. Here is what is displayed when this happens.
Chrome version 12.0.742.122
