           Summary: [ARM] Ambiguous implementation of char
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dbatyai.u-szeged at partner.samsung.com


In c++ the signedness of char can be implementation dependent. Unfortunately, this caused the incorrect handling of Unicode characters in JavaScriptCore on ARM, since the code in stringFromUTF8 in jsc.cpp (http://trac.webkit.org/browser/trunk/Source/JavaScriptCore/jsc.cpp#L658) assumes that char is signed, but that was not the case on ARM.
