I thought this would give me the length of the string, but it seems to be counting words instead:

zsh% echo ${#$(echo hello)}

Is this a bug? I thought I'd need a modifier flag to treat output as an array and give me a word count, while character count would be the default.

Process substitution gives you an array. Quote it if you need a scalar.
