Unique code-point range

None of the supported code sets have bytes 0x00 through 0x3F in any byte of a multibyte character. This group of code points is called the unique code-point range.

These code points always refer to the same characters as specified for 7-bit ASCII. This is a special property governing all supported code sets. ASCII Characters in the Unique Code-Point Range (ASCII characters) lists the characters in the unique code-point range.
