Our engineers have made some changes that will hopefully correct the problem for at least some users that are having this problem. Please let us know whether or not you are still having this problem, and also what type of character encoding you are using on the internet browser that has/had the problem. (Please note that if it is working on one browser, and not on another, then we would need the information for the browser where it is not working.)
In Firefox you may locate this under "Tools" --> "Content" --> "Fonts & Colors" --> "Advanced" --> then locate what is selected in the "Default Character Encoding" drop-down box. Also, is the box "Allow pages to choose their own fonts, instead of my selections above" selected here?
In Internet Explorer, go to "Tools" --> "Internet Options" --> "General" --> "Fonts" --> what options are selected here? Also, from the "General" tab click "Accessibility" and you should see four boxes, with the first three beginning with the word "Ignore" --> are those first three boxes checked or not checked?
