UnicodeRanges static properties return incorrect range

Description

UnicodeRanges provides several static UnicodeRange properties corresponding to Unicode code blocks. For some of these properties, the returned range is not equivalent to the range stated in the documentation.

For example, UnicodeRanges.BasicLatin is stated to return the range from U+0021 to U+007F, but actually returns the range from U+0000 to U+007F.

The only two ranges I have found to be incorrect are BasicLatin and Latin1Supplement (range starts at U+0080 instead of U+00A1), although there could be other instances.

We read the ranges from the official Unicode Blocks File and it has the ranges as we return it:

0000..007F; Basic Latin
0080..00FF; Latin-1 Supplement

So, we return the correct results according to the published Unicode Standard files.

Forgive my wording. The blocks are correct as per Unicode standard, but the .NET documentation page lists a different range.

Oh, sorry.

Are you interested in submitting a PR to fix that? Thanks!
