In one of my work projects it was the Turkish İ that gave us trouble. In some case-insensitive text searching code, we matched the lowercase query against the lowercase text, and had to handle cases like that specially to avoid reporting the wrong matching span in the original text, since the lowercase string would have a different length than the uppercase string. This was one of my first real-world projects and opened my eyes a bit to the importance of specifications and standards.

I haven't had this experience with TypeScript. In the projects I've worked with, we turn on strict mode and heavily discourage using `any`. I generally feel pretty confident that the type annotations match the runtime values.

But where do you store the URL for the S3 bucket? Can you really say it's usefully preserved if nobody knows the URL (or the account credentials)?

IMO the formatting of the error string returned by errors.Join is atrociously opinionated and not very logging-friendly - it adds a newline between each error message. I know I'm not the only one that has this opinion

I think you are conflating ES6 classes with TypeScript.
