Thanks very much for doing that, but as you say this doesn't seem 
to be the right place to look for language settings.

Thanks; but I don't see anything unusual there.

I'd really like to find out what's happening here.  I've built a 
new gretl snapshot, at

http://ricardo.ecn.wfu.edu/pub/gretl/gretl_install.exe

which prints out some debugging information for graphs.  If you 
could download and try this version that would be much 
appreciated.  To see the debugging info:

* Use the Start/Run Windows menu item

* Browse and select gretlw32.exe (under Arquivos de 
programs\gretl?)

* Append " --debug" to the path to gretlw32.exe (that's a space 
followed by two dashes, followed by debug, typed without quotes):

"C:\Archivos de programas\gretl\gretlw32.exe" --debug

* Hit OK to run, and you should see gretl accompanied by a console 
window, in which the debugging information will be printed.

A good test case is this: open the Ramanathan dataset data3-6; 
select both Ct and Yt in the gretl main window; right-click and
select an XY scatter plot (this will definitely produce accented 
characters in the graph).

For reference, I'm showing below the output I got when I did 
exactly that, running on Windows XP with Brazilian Portuguese 
selected.  Some of the lines will be broken in the email, and some 
of the characters are not represented correctly since the original 
output was in UTF-8, which is not supported in the Windows
console, but it gives the idea.  In my case the graph displays 
correctly.
