toolchain/check/testdata/builtins/char/basics.carbon and toolchain/lower/testdata/builtins/char.carbon are probably the most interesting tests here. The parse tests is required because this adds a new node kind, and we need coverage of it; but the attached info is minor. There's a fair amount of test churn here because I'm adding the Core.Char and Core.CharLiteral types as new singletons. My intent here is that `CharId` is always a unicode code point, even when the type is a `Char` and thus must be a single UTF-8 code unit (single byte). This mainly means the stored value of a `CharValue` can be printed internally without knowing the type. --------- Co-authored-by: josh11b <15258583+josh11b@users.noreply.github.com> Co-authored-by: Richard Smith <richard@metafoo.co.uk>
