Please update the VB language specification to clarify what case-insensitive means.

[gafter]

The Roslyn VB compiler interprets "case-insensitive" to to mean "the same when individual characters are mapped to lower-case using the one-to-one Unicode lower-case mapping (i.e. the Simple_Lowercase_Mapping field from UnicodeData.txt, which excludes mappings that would result in a single character being transformed into multiple characters).

We are now taking language feature discussion on https://github.com/dotnet/csharplang for C# specific issues, https://github.com/dotnet/vblang for VB-specific features, and https://github.com/dotnet/csharplang for features that affect both languages.

See also #18002 for a general discussion of closing and/or moving language issues out of this repo.
