Questions for writing manpages

[Franklin PIAT]

Hello,

I have some questions for the writing the documentation[1].

** How to use "If [ $x=foo ] Then Else fi" statement ? 

I've successfully used :
 if [ A=B ] ; then echo "foo" ; else echo "bar" ; fi" 

But I cannot use variables, with either :
 if [ $i=B ] ; then echo "foo" ; else echo "bar" ; fi" 
 if [ X$i=XB ] ; then echo "foo" ; else echo "bar" ; fi" 


** How would you define the "rescue" mode ? In what situation 
can it be useful to the user ?

** Does the "ofconsole" console supports unicode ?

Thanks for your help.

Franklin
