charcode is only used by TextSelectionPainter::visitWord.  (If it was used by
anything else we'd see ligatures being repeated.)

If the start of the selection is halfway through a ligature, we need to walk
backwards to find the "real" character at the start of the ligature.  Cleaned
up and simplified.
