xunicode transforms LaTeX's explicit non-ASCII character calls (such  
as \'e, \`a, \textemdash, \textbullet and so forth), generally  
implemented as macros at the TeX level, into calls to the  
corresponding Unicode characters.

Mapping=tex-text transforms LaTeX's implicit non-ASCII characters  
calls (such as --, ---, and similarly for the Spanish inverted  
question and exclamation marks -- I don't remember the input for  
them), generally implemented as ligatures as the font metrics level,  
into calls to the corresponding Unicode characters.

The technical terminology above is probably erroneous, but I hope you  
get the idea.
