           Summary: [GTK] font rended incorrectly when using a English
                    font-family name in css definition
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED

Recently I have been devoting myself to  development of a browser-like software using webkitgtk on the platform of Ubuntu 13.04 AMD 64 distribution. But I find a fairly inscrutable problem when webkit rending Chinese font. The situation is described below:
    Firstly, The official webkit demo /usr/lib/webkitgtk-3.0-0/libexec/GtkLauncher can't rend the correct font which a webpage assigned by css definition. For example, a webpage assigned the font family as "Microsoft Yahei"，but the GtkLauncher just rend Simsun font for all text. I should considered that it is because that I haven't install the MS Yahei font into my system. But after I install it, the problem remains. And in other browsers using webkit like chrome, it always rend the right font, including the Chinese font.
    When I try to solve the problem, I find some tips, but still block. I have noticed a phenomenon: when setting the font family to Chinese name instead of English name in the css definition, it does rend the correct font!. In other words, I just alter the the definition like this:
    some-element{font-family:"Microsoft Yahei"}  ---> some-element{font-family:"微软雅黑"}
    Then it works! And I checked other Chinese font like WenQuanyi font family, it appears the same problem. But generally speaking, you'd better to write in English when set a font-family name attribute . But now the English name don't work, on the contrary, the Chinese name works, it is really confused.
    In addition, I still can't distinguish where the bug exists, is it in webkitgtk or Ubuntu 13.04 system. I have searched the solution for some time on the Internet, and tried some method, but all failed. So I commit this bug to you, expect your reply!
