Allin,

    I really think the problem is related with the languages pt e pt_BR. When I start gretl with
the command line "Applications/Gretl.app/Contents/Resources/bin/gretl" I get the Brazilian-Portuguese version and it works fine. So I need to discover how to configure my Mac to use Brazilian-Portuguese in gretl in the same way my other softwares work.

Best,
Henrique

Therefore, it seems this experiment might be worth trying: in a
terminal window, do

export LANG=pt_BR.UTF-8

then try "locale" again and see if LC_ALL appears set.
 
I did these procedures but LC_ALL remains the same (blank).
 
  (...) try starting gretl from the terminal, using the shell script named

"gretl" in Gretl.app/Contents/Resources/bin .  Do accented
filenames then work?  If so, the problem is associated with no
value being given to LC_ALL.

I did these procedures and the accented filenames had worked. But I'd noticed that when I open gretl using the icon (with double click) it starts the Portuguese version (from Portugal), while using the command line "Applications/Gretl.app/Contents/Resources/bin/gretl" I get the Brazilian-Portuguese version.

I also tryed to work with accented filenames using Windows XP and gretl worked fine.
