In the attached example, the displayed text is: GRÖSSTEN The source html has: <span style="text-transform:uppercase;">größten</span> If you call WebCore::findPlainText and try to find the letter "n" we hit an assert. This happens because TextIterator finds the N with an offset of 8 (based on what is displayed). When it tries to convert that to a DOM Range, it tries to set an end offset of 8, which is beyond the end of the actual HTML. This triggers an assert at WebCore/dom/Range.cpp:87. Is there a helper method for converting between offsets in the rendered text and the source text? I didn't see one in RenderText. I see a similar bug when trying to select the word using double click (it doesn't select the last character of the word).

This might be close enough to bug 8854 to be called duplicate. There are a few more tangentially related bugs filed earlier.
