Thanks for the detailed answer Ulrik, although it seems like there's not much I can do but learn LuaLaTeX in order to get the documents as I want them to be. :)<br>Would it be possible to get the LuaLaTeX code you used in order to compile the document as a starting-point, as I've never seen or tried it before?<br><br>Best regards,<br>D.<br><br>> Date: Mon, 16 Aug 2010 00:15:35 +0200<br>> From: ulrik.vieth@arcor.de<br>> To: xetex@tug.org<br>> Subject: Re: [XeTeX] Problems with thickness of \frac rule and width of accents (\hat) with XeLaTeX<br>> <br>> Hi,<br>> <br>> I tested it with both XeLaTeX and LuaLaTeX (both from TL2010 pretest).<br>> In short, the problem only occurs in XeLaTeX, but not in LuaLaTeX,<br>> despite using the same macro packages and fonts for both engines.<br>> <br>> I do not really understand the problem with the fraction rule thickness.<br>> It probably should be the same on both engines (despite conceptual<br>> differences), as it should be based on the same OpenType parameter<br>> RadicalRuleThickness, but it seems to be different nonetheless:<br>> <br>> XeLaTeX:<br>> .......\kern4.7461<br>> .......\rule(0.47998+0.0)x*<br>> .......\kern2.97542<br>> <br>> LuaLaTeX:<br>> .......\kern3.43199<br>> .......\rule(0.79199+0.0)x*<br>> .......\kern2.98799<br>> <br>> The LuaTeX value of 0.792pt at 12pt matches the scaled value of 0.66pt<br>> at 10pt of the OpenType font parameter for XITS Math.<br>> <br>> The XeTeX value of 0.48pt at 12pt matches the scaled value of 0.4pt<br>> at 10pt, which is suspiciously similar to the default rule thickness<br>> of CM fonts.
