I tried many of the chinese utf8 fonts, and none of them works in Hikaserial.

where to download the one that is working? tried google font for chinese. they don't have ttf (only OTF), and hikaserial only supports ttf. I tried to convert it, but still not working.

Hi,

For example, this page has ttf fonts for Chinese, some for traditional, some for simplified:
www.wildboar.net/multilingual/asian/chin...t/non-microsoft.html
It's the second link I got on Google when searching for Chinese fonts.
And you can even find on Google MicroSoft fonts for Chinese that they use in Windows. For example:
