Bug #20991: Prism parses `"\C-\α"` into `"α"` which should be syntax error
https://bugs.ruby-lang.org/issues/20991
* Author: tompng (tomoya ishida)
* Status: Open
* ruby -v: ruby 3.5.0dev (2024-12-27T07:27:30Z master adbbc9109e) +YJIT +MN +PRISM [arm64-darwin22]

$ ./ruby -e 'p "\C-\α"'
"α"

I think it should raise `Invalid escape character syntax` just like `"\C-α"` does.
~~~ruby
"\C-α"
# Invalid escape character syntax
"\C-\α"
# Prism: "α"
# parse.y: invalid multibyte char (UTF-8), reported in #20990
