[Csaba Osztrogonác]

All API tests pass with the latest pinned Qt5 hash (7d0327830bb4768753cb0c14a23d98fed08be7d2),
but the following test fails with a newer Qt5: 15f3399576bd433898f8e89bbcb3c1196e0da5b9

FAIL!  : qmltests::WebViewPreferences::test_standardFontFamilyChanged() Compared values are not the same
   Actual   (): 'Bitstream Vera Serif'
   Expected (): Bitstream Vera Serif
   Loc: [/home/oszi/WebKit/Source/WebKit2/UIProcess/API/qt/tests/qmltests/WebView/tst_preferences.qml(204)]

Thanks for finally fixing this one, Marcelo :-)  I have some comments following.

I would rephrase this, at least to make clear is our: __WebView__ experimental preferences API. And we return the same values as existing WKPreferences C API for WK2.

Can we make it simpler? Like /^'?(.*)'?$/, '$1'... or even no Regexp at all.

This still doesn't support fonts that had ' originally in the name, but since our set of fonts is controlled for testing, that should be OK.

> Source/WebKit2/UIProcess/API/qt/tests/qmltests/WebView/tst_preferences.qml:210
> +                compare(unquote(webView.title), unquote(defaultStandardFontFamily))

Just need to unquote the webView.title here since we expect defaultStandarFontFamily to be unquoted.

Bah. My suggestion is wrong because (.*) will eat everything. But I still think we can simplify this.

Is it on the spec?

"To avoid mistakes in escaping, it is recommended to quote font family names that contain white space, digits, or punctuation characters other than hyphens (...)"
