Quibbles about characters and code points

There are 1,114,112 code points; as of Unicode 15.1 (2023), fewer
than 150,000 have been assigned to characters. It is difficult to
specify that unassigned code points should be avoided because they
regularly become assigned when new characters are added to Unicode.

Section 2 of the I-D provides a description of characters and code points for local use in the document. The above quoted paragraph might be improved by:

• mention the hex size of the code point space (0x10FFFF or 0x10FFFD if you prefer) next to the weird decimal number.
• the phrase "It is difficult to specify that unassigned code points should be avoided" understates the problem. We explicitly do not want to forbid unassigned code points that later do become assigned.
