Bug: ASCII range mentioned as U+0001..U+007F, rather than U+0000..U+007F

[ezequiel-garzon]

Describe the bug

Section 2.3. Identifiers and keywords of the python.org language reference indicates:

Within the ASCII range (U+0001..U+007F), the valid characters for identifiers include the uppercase and lowercase letters A through Z, the underscore _ and, except for the first character, the digits 0 through 9.

But the ASCII range is U+0000..U+007F, not U+0001..U+007F. The documentation points to PEP 3131, where the same range is used.

To Reproduce

Visit the referenced webpage.

Expected behavior

Unicode's first block, with "Range: 0000..007F" (second line of U0000), is known as Basic Latin or C0 Controls and Basic Latin. The official charts index page refers to it as Basic Latin (ASCII), emphasizing the historical connection with the older standard.

Therefore, if it is deemed necessary to clarify the ASCII range at all, it should be U+0000..U+007F, not U+0001..U+007F.
