In /usr/local/texlive/<year>/texmf-dist/fonts/misc/xetex/fontmapping/ 
base you'll find tex-text.map and tex-text.tec. The former is the  
text or source file, with a simple input format. There you'll find  
the rule to convert APOSTROPHE at U+0027 to RIGHT SINGLE QUOTATION  
MARK at U+2019. The ";" is a comment character, so you could easily  
disable this particular rule. The programme teckit_compile, coming  
with TeX Live 2009, creates the binary .tec version which XeTeX uses.

In pdfTeX you can use CMAP files to tell the PDF viewer how to map a  
sequence of text representing bytes to a particular character. On the  
command line "texdoc -l cmap" will show you some docs on the topic  
"CMAP." Use the simple README text file. It explains a few things.  
In /usr/local/texlive/<year>/texmf-dist/tex/latex/cmap you'll some  
example CMAP files Vladimir Volovich provides. And also the STY file,  
which should be loaded very early.
