How do you use Data.Text.intersperse :: Char -> Text -> Text?

[Carter Schonwald]

Cool!
Looks like the approach there is to not have a character type, but treat
code points as just tiny strings which can be mapped to integers?

I kind have this fuzzy idea Haskell and a lot of other languages use the
extended ascii character set in a sortah punned way that conflates binary
and textual data.  And that’s ignoring how most western / native English
software folks naively treat  chars as graphemes / atomic units of
rendering, when this falls apart when engineering for internationally
friendly software.
