Missing unicode? characters

[anonuser]

I ran into some problems when noscript is activated. For example, on the following site there are tabs "Page" and "Discussion" on the top. Besides "Discussion", there seems to be something like a UTF-8 character, which maybe originates from a CSS. This character (a drop-down arrow) is not visible, instead a small box with four hex digits (F0F6 or similar) is shown. I've tried allowing the site, to no avail. What is going wrong here? I'm experiencing this on other sites too. If I reset noscript, the characters are shown correctly.

Ok, I've played around a bit more with the settings and stumbled over blocked objects. I've enabled to download a font, and now everything works as expected.
