10,646
ISO/IEC 10646 defines the Universal Coded Character Set, kept in step with Unicode.

Where 10,646 fits
Why 10,646 is special
Two separate bodies standardise the same character set and have committed to keeping them identical, because a divergence would split text encoding worldwide. The duplication is a historical accident maintained deliberately.

1 × 10,000 + 6 × 100 + 4 × 10 + 6 × 1 = 10,646. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
ISO/IEC 10646 and Unicode define the same character set and are kept synchronised deliberately, and code page 65001 is how UTF-8 reached a system designed long before either.

Technology & computing
Unicode and ISO/IEC 10646 are maintained by different organisations and synchronised character for character. The duplication is inherited from a period when both were proceeding separately, and it is preserved because divergence would be catastrophic for text interchange.
