I described the format here: http://lists.gnu.org/archive/html/grub-devel/2004-05/msg00020.html GRUB 2 contains a script unifont2pff.rb in the directory util.

I had the idea to start a Unicode debate on how to handle this. My first idea would be : unsigned int grub_putcode(...); unsigned int grub_putchar(...); Ignoring the return value would make those function act as they do now. Reading it would give the number of char actualy displayed on screen. 0 = Unicode char incomplete (for putchar only, for putcode might be "invalid Unicode" if applies) 1 = one char written 2 = a char as wide as 2 "usual chars" (I think I read somewhere it exists) (and so on) I was also wondering about the font format.

As you all know, unicode, i18n, etc still confuse me a lot. :) -- Marco ___ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel

Yeah, personally I prefer pointers to do this. how about adding:
inline unsigned
grub_getx (void)
{
return grub_getxy () >> 8;
}
Or a macro or so which does the same.
Thanks,

This sounds like a bug in the terminal to me. In that case it has to be fixed in the terminal and not corrected in the menu.

Right.
My first idea was to use a struct as return type :
struct coords {
unsigned char x;
unsigned char y;
};
So it becomes :
if (grub_getxy () .x)
Or maybe a struct of bitfields...
I feel structs as being cleaner to use compared to shifts. If someday
we have a terminal that exceeds 255 chars in one or both dimensions, we
wouldn't have to grep "grub_getxy ()" to find the shifts...

For example, when I just want to know if the position is 0 or not in the x axis, I can do this in the current API: if (grub_getxy () >> 8) But if I need to use a pointer, this becomes: unsigned x; grub_getyx (0, &x); if (x) Well, this might be just a preference.

You can check in this patch, but this is not the right thing to do. At the moment, it is impossible to know how many columns will be occupied by putting a byte until it is actually putted. This is very bad, and, of course, does not work well in some cases. So, as I described before, it is necessary to implement a new function which returns the width for a given (Unicode) character. For the menu, I think it would be easier to convert all strings to Unicode strings before rendering. Writing bytes is very, very hard.

There is an alignment problem when menu is drawn with Unicode chars in
titles : there aren't enough spaces written on the right to make the
hilight fill horizontaly the menu.
