Bug 120096 – REGRESSION (r145458?): WebProcess doesn't respect UI process localization

• Component: WebKit2
• Status: RESOLVED FIXED

[Alexey Proskuryakov]

Running UI process with -AppleLanguages argument no longer results in a matching localization in WebProcess.

Also, WebKitTestRunner fails to set WebProcess localization to English.

I don’t think we need all three local variables. Maybe get rid of cfLocalization? Why use String::format when concatenation has much better performance? I would write this single-line version:

    CString appleLangagesArgument = ("('" + String(adoptCF(WKCopyCFLocalizationPreferredName(0))) + "')").utf8();
