:a hint for single ASCII chars?

[allexoll]

I ran into a surprise using the :a hint when using it with single characters, they print as decimal:

let v:u8 = 97; // 'a'
let bytes = [104, 101, 255, 108, 108, 111];
defmt::info!("{=[u8]:a}", bytes); // -> INFO b"he\xffllo"
defmt::info!("{=u8:a}", v); // -> INFO 97

Is that the expected behaviour? This can easily fixed on my end by doing [v] but i was surprised none the less

feel free to close this if it is expected behaviour

Hi @allexoll, Thank you for opening this conversation.

There is nothing which speaks against the :a display hint supporting chars as well. It was just not asked for so far.

Would you be interested in implementing it? We can guide you through it.

Have a great day! 🌥️
