Simple Lightbox breaks font type's accent support outside of lightbox

[kazerniel]

Description of Problem

I manage a site in Hungarian language. We use the font Yanone Kaffeesatz for headers, which does support all Hungarian characters, including "ő".

We use the Simple Lightbox plugin on a single page, and there it turns the "ő" characters in the headers into the sans-serif fallback.

Not sure if this is related to #1032, as we don't use text captions in the lightbox, instead the plugin breaks the font of headers on the page itself.

I tried deactivating plugins to find the cause, and when I deactivated Simple Lightbox, the problem was resolved.
