The original Unicode code space ran from U+0000 to U+FFFF, a space of 65,636 code points. Since then 16 more spaces of that size have been added, for a total of more than a million code points. Several writing systems for dead languages have been put into this extra space, and so have five-digit Unicode hex code point numbers. | The original Unicode code space ran from U+0000 to U+FFFF, a space of 65,636 code points.
