Problem with non-ascii filenames on a non utf-8 locale

[Michel Boaventura]

Hello,

More about the filename issue:

Glib manual says (on 
http://library.gnome.org/devel/glib/stable/glib-Character-Set-Conversion.html#file-name-encodings-checklist):

"If you get a file name from the file system from a function such as 
readdir(3) or gtk_file_chooser_get_filename(), you do not need to do any 
conversion to pass that file name to functions like open(2), rename(2), 
or fopen(3) — those are "raw" file names which the file system understands."

If I understand this right, since we get filename directly from the 
command line, we don't need to convert
it to open the file. If the locale support utf8 or not, we will get the 
string on the same locale that
we need to open the file. So we may not need the two step conversion 
from load_data_file function.

But we do need to convert it to show the name on syntax:
"If you need to display a file name, convert it to UTF-8 first by using 
g_filename_to_utf8()..."

I don't know if this function is used to open file in other contexts, 
like syntax files, or File -> Open menu but, if not,
I think we should get rid of the two step conversion from load_data_file 
function.

What you think?

Regards,

Michel
