sti_select_fbfont() and sti_cook_fonts() are hard-coding the number of characters of our built-in fonts as 256. Recently, we included that information in our kernel font descriptor `struct font_desc`, so use `fbfont->charcount` instead of hard-coded values. This patch depends on patch "Fonts: Add charcount field to font_desc".
