On OS-X/Mac (in natively based Cocoa text) the problem is solved by having a "split caret".
In situations where the logical position of the insertion point between characters map to two locations (in the rendered text) -- e.g. at the boundary of a RTL/LTR block, the "usual" line-high vertical insertion bar is visually split into a top-half that indicates where LTR text will (appear to visually) be inserted and a bottom-half that indicates where RTL text will (appear to visually be) inserted. That is the caret simultaneously occupies two positions in the rendering.
