Yes, it doesn't correspond to the space's advance width, which depends
on the font (unlike the x_ppem which only depends on what you ask in
FT_Set_Char_Sizes or FT_Set_Pixel_Sizes)

The best way is simply to use something like:

   glyph_index = FT_Get_Char_Index( face, 32 );   /* get glyph index for space 
*/
   error = FT_Load_Glyph( face, glyph_index, FT_LOAD_DEFAULT );
   space_advance = face->glyph->metrics.horiAdvance;

Hope this helps :-)
