[XeTeX] Bug report \XeLaTeX and \XeTeX logos

[Peter Dyballa]

Hello!

The \XeLaTeX and the \XeTeX logos from xltxtra.sty are typeset  
differently, on the same line, with the same font. Particularly the  
difference (or kerning) between the first X and the lowered Ǝ (LATIN  
CAPITAL LETTER REVERSED E, U+018E, here, in the logo actually  
reversed by rotating thanks to graphicx package, where it's real  
funny when slanted or italic or handwritten):

In the first instance the kerning seems to be switched off, in the  
reprise it's on and OK. My LOG file tells:

The code I used is:

	\documentclass[a4paper,12pt]{article}
	  \usepackage{xltxtra}
	  \defaultfontfeatures{Mapping=tex-text}
	%  \setromanfont{Baskerville}
	%  \setromanfont[ItalicFont={HiraMinPro-W3:+ital},BoldItalicFont= 
{HiraMinPro-W6:+ital},BoldFont={HiraMinPro-W6}]{HiraMinPro-W3}
	%  \setromanfont[ItalicFont={HiraKakuPro-W3:+ital},BoldFont= 
{HiraKakuPro-W6},BoldItalicFont={HiraKakuPro-W6:+ital}]{HiraKakuPro-W3}
	  \setromanfont{ヒラギノ丸ゴ Pro W4}	% Hiragino Maru Gothic Pro
	
	\listfiles
	\begin{document}

	habitudes et un certain entre auteurs et \XeLaTeX\ éditeurs.  \XeLaTeX
	
	habitudes et un \textit{certain} entre \textbf{auteurs} et \XeLaTeX\  
\textbf{\itshape éditeurs}. \XeLaTeX\
	
	\end{document}

Baskerville does not show the effect, and also some other Latin  
script fonts, neither do Korean or Chinese fonts. The Japanese  
Hiragino fonts show it, except Osaka. (They're all fonts in Mac OS  
X.) And the last line *only* shows the effect when I use a font that  
does not have all the variants.

Mac OS X 10.4.11, TeX Live 2008 from MacTeX August 2008. This is  
XeTeXk, Version 3.1415926-2.2-0.999.6 (Web2C 7.5.7)
