Hello,
My thesis is finished soon, but I have an annoying apostrophe problem.
In French we have a lot of apostrophes uses like this : L'œil, l'incertitude,
etc.
In theory, these apostrophes should be the unicode character U+2019 (right
single quotation mark) instead of a straight apostrophe (U+0027). This
replacement is automatically made by this command :
\defaultfontfeatures{Mapping=tex-text}
First there is a problem with the kerning of this U+2019 character, it is
possibly a bug in the font I'm using (Adobe Caslon Pro), but I'd like to solve
it anyway.
Here is an example (The word L'œil, on the top right) :
http://dl.dropbox.com/u/1205127/Images/xetex.jpg
The apostrophe is completely kerned above the "œ" (the same problem is present
for any small character), which thus touches the "L".
So my first question is: is there a way to override the default kerning of this
U+2019 character so that it behaves in a more correct way (with a slight space
between the apostrophe and the next letter) ?
Now there is a second problem (which solved the first one but in a bad way).
When activating margin kerning, xetex behaves as if the line
\defaultfontfeatures{Mapping=tex-text} was not present : U+0027 apostrophes
stay straight (which curiously solves the kerning problem, see the example on
the top left of the image), and `` and '' are not converted appropriately (more
annoying).
Here is what I use for the margin kerning (when I comment these line, the
mapping problem is corrected) :
\newcount\countA
\ifx\XeTeXprotrudechars\undefined
\pdfprotrudechars=2
\else
\let\pdftexversion=\countA
\pdftexversion = 140
\XeTeXprotrudechars=2%\fi
\input protcode-native
\font\f="Adobe Caslon Pro" at 11pt \f
\setprotcode\f
\pretolerance=-1
\tolerance=9999
\emergencystretch=2em
With the file protcode-native file being
\def\setprotcode#1{
\rpcode#1 U"0021 55
\rpcode#1 U"002C 194
\rpcode#1 U"002D 233
\rpcode#1 U"002E 194
\rpcode#1 U"003B 138
\rpcode#1 U"003A 138
\rpcode#1 U"003F 94
\lpcode#1 U"2018 194
\rpcode#1 U"2019 194
\rpcode#1 U"0027 194
\lpcode#1 U"201C 250
\rpcode#1 U"201D 250
\rpcode#1 U"2013 150
\rpcode#1 U"2014 200
}
So, in short, I want to use margin kerning while maintaining the tex-text
mapping AND having a correct kerning with the U+2019 apostrophe.
PS: (this last problem also appears on my sans serif font (Myriad pro), an
example is visible in the linked image.
Thank you,
Pierre
