Something tells me that you never ventured outside of writing English, because in any other language, having strings in unicode rather than ASCII is a huge improvement.

Then, Python3 has type annotations, which lets you use mypy to do some static checks on the code.

I wrote typedload (https://github.com/ltworf/typedload) to load json-like data into typed data structures, so that once loaded, you know your data has the correct types and can be safely be passed around.

My grandmother did not know how to use a computer, that doesn't mean that computers are useless.

JFYI, my native language is Russian so I’m acutely aware of encoding problems since so many of them were used for Cyrillic scripts. I can speak Ukrainian and understand Polish and Czech. I’d used to be able to speak German but haven’t practiced it in decades and lost most of it. Now I’m also studying Mandarin Chinese for a change.

Static annotations are nice, but are kinda beside the point.

Except that Python 2 strings aren't ASCII and support Unicode perfectly well: you just put UTF-8 inside them.

They work but are very error prone, because characters might take any amount of elements, so you have all sort of issues when doing cycles or manipulation.

With unicode objects, you know that they are not array of bytes and a conversion is needed, and you get an error if you didn't do the conversion that you were supposed to do.
