U+: pretty Unicode code point literals for Rust

Given the known issues I don’t think there’s much practical use for this; it’s just fun. The one place where I plausibly had an excuse, I preferred to just enter the character directly.

  ('ffi', "ffi"),
  ('ſt', "ft"),
  ('st', "st"),
  ('[U+2001 eaten by HN]', "    "),

For invisible characters my editor shows a colored placeholder with the codepoint on hover.
