This is actually a font issue, as well as a rendering engine issue. Technologies like OpenType and Graphite allow the specification of attachment points for accents, so that unanticipated forms can be drawn. Of course, the rendering engine has to know enough to take advantage of that, too. I have on my docket drafting a UTR on the subject with a list of precomposed glyphs which would be desirable in fonts and available to end users. ========== John H.
