"Attempt to insert nil value " exception when calling attributed string APIs on content with a custom font

I'm not sure if the way I'm referencing the font in the TestWebKitAPI project file is kosher.  If it is not, I can just check in another copy of Ahem.

Can this just use a layout test instead? We expose these methods through textInputController in DumpRenderTree. WebKitTestRunner is currently more limited, but it will definitely support this eventually, too.

I do have a layout test that works in DRT, but since I couldn't get it to work in WebKitTestRunner, even while trying to add the feature to textInputController, I switched to making an API test.  I couldn't figure out how to call attributedSubstringForProposedRange from WebKitTestRunner/InjectedBundle/TextInputController.cpp.  Do you think that is possible?

I see, so the issue here is that we need to do the conversion in another process. That won't work with textInputController indeed.

If you have attributedSubstringForProposedRange implemented in WTR, I'd encourage you to see if you can land that and unskip some of the tests that are currently skipped in mac-wk2.

Patch looks good to me, but I don't know the answer to your question about Ahem.

No, I just have an empty implementation.

Please give TestWebKitAPI its own copy.

You could have used EXPECT_WK_STREQ here. When it fails, prints the actual string (as opposed to just the fact that it’s not the expected one).

That's what I had in there, but I didn't want to be presumptuous :)
