Having trouble implementing Chinese language in a CEP panel

Hi everyone

Couple questions regarding using chinese as a language in a CEP panel.

First about the flyout menus, I tried to use this string as one og the language options "中文"

but I get this result:

Second, the same happens within my panel UI.

Tried changing to a couple fonts but without luck.

It would be awesome if anyone that implemented something like this

could point me in the right direction.

Many thanks
