# char-at
The character at CODEPOINT index n — the same coordinate system as
`nth`/`slice` (never a raw byte fragment; `byte-at` for binary).
## Syntax
[char-at $string $n]
## Examples
[char-at "hello" 0] # "h" [char-at "a中c" 1] # "中" [char-at "hello" 9] # nil (out of range)
## Returns
Single-character string at the index, or nil if out of range.
