Which version of firmware do you use?
For older versions (2.0.x), the default browser is midori and you can use chinese fonts by installing rias'
modified midori browser
New 2.1.2 firmware differentiate between touch and non-touch screen devices. I guess, 612 should use arora browser which I have no information at all. There is no actually working webbrowser for 60x/90x in the fw 2.1.2.
The modified midori is not working at the new firmware. It is started, but it does not respond to any key except the "exit" button.
