inline fun <V> CharSequence.associateWith(
    valueSelector: (Char) -> V
): Map<Char, V>

Returns a Map where keys are characters from the given char sequence and values are produced by the valueSelector function applied to each character.

If any two characters are equal, the last one gets added to the map.

The returned map preserves the entry iteration order of the original char sequence.
