Handle invalid chars better, and do small cleanups around error output. (#657)

mirror of https://github.com/carbon-language/carbon-lang.git synced 2026-10-05 20:42:01 +01:00

This adds a test for invalid characters (that would've failed before, because the printed char isn't escaped). Not sure if there's a good way to test the PrintDiagnostic code, as it appears to occur on bison parser errors, which I'm just not sure how to trigger.
