The suggestion there is to use a font like </SPAN></FONT><FONT class="Apple-style-span" color="#000000"><SPAN class="Apple-style-span" style="background-color: transparent;">Doulos SIL, which includes features for stacking arbitrary diacritics signs that work in XeTeX.</SPAN></FONT></DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The same problem (XeTeX overlaps, instead of stacking, diacritics in pdf output) occurs when combining, say, U+0117 (Latin Small Letter e with dot above) with U+0301 (Combining Acute Accent). The output is fine with Doulos SIL, but not with other fonts (e.g. Gentium). I was wondering whether the reason for this behaviour still depends on the text rendering engine, since in this case I am not stacking two "combining accents", but rather a "letter" with an accent (I guess U+0117 should be considered as a unique symbol, not a combination of 'e' with an accent).</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>(My apology if this question is trivial or my terminology not appropriate: I am not a Unicode or font expert)</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Nicola</DIV></BODY></HTML>
