Hi,<br>
<br>
Just wondering if any one know of a good web site covering<br>
whether/when to use XeLaTeX or not.<br></blockquote><div><br></div><div>Have you ever dropped by the TeX Stackexchange? It is the perfect place to find answers to such questions:</div><div><br></div><div> <a href="http://tex.stackexchange.com">http://tex.stackexchange.com</a></div>
<div><br></div><div>Here's a question that asks about the differences between XeTeX and LuaTeX (which are the engines that power XeLaTeX and LuaLaTeX):</div><div><br></div><div> <a href="http://tex.stackexchange.com/questions/36/differences-between-luatex-context-and-xetex">http://tex.stackexchange.com/questions/36/differences-between-luatex-context-and-xetex</a></div>
<div><br></div><div>Also a question that asks about XeTeX/LuaTeX compared to pdfTeX and if there are any drawbacks:</div><div><br></div><div> <a href="http://tex.stackexchange.com/questions/3094/drawbacks-of-xetex-luatex">http://tex.stackexchange.com/questions/3094/drawbacks-of-xetex-luatex</a></div>
<div><br></div><div>Remember that LuaTeX is under heavy development, so issues mentioned last year may not be present in TeX Live 2011. And of course, all the questions tagged as having to do with XeTeX **and** LuaTeX:</div>

Looked at <a href="http://wiki.xelatex.org/doku.php?id=start" target="_blank">http://wiki.xelatex.org/doku.php?id=start</a> but I ma no<br>
clearer as to the status of XeLaTeX - having seen remarks around the<br>
web that it does not yet work with all the packages that pdfLaTeX<br>
does, just wondering what the status of XeLaTeX is please - any<br>
pointers/ appreciated.<br>

Compatibility issues with LaTeX have generally been worked out---however a key difference to be aware of is that internally XeTeX compiles to DVI and then creates a PDF using `dvipdfmx` while LuaTeX compiles directly to PDF just like pdfTeX does. So, any packages which are dependent on the "direct-to-PDF" pipeline of pdfTeX may have issues under XeTeX.</div>
<div><br></div><div>Personally, I get the feeling that XeTeX has more active users with more collective years of usage behind it __right now__ and thus is more stable and tested. LuaTeX is still officially in beta but has powered the ConTeXt MK IV engine for quite a while which makes a good argument for its stability. LuaTeX also adds many more features and is the officially designates successor to pdfTeX, so I expect it will eventually eclipse XeTeX in usage in the years to come.</div>
<div><br></div><div>Some data points---one of my college buddies who really got me into TeX switched to XeLaTeX about a year ago and has been loving it. He recently started his Ph. D. work so he gets some heavy usage out of the engine.</div>
<div><br></div><div>Personally, I'm slowly drifting from pdfTeX to LuaTeX.</div><div><br></div><div>-Charlie</div>
