getOrDefault

fun CharSequence.getOrDefault(index: Int, default: Char = ' '): Char(source)

Gets the character at the given index, or returns the default value if it's out of bounds. The default is ' ' (single whitespace) when unspecified.

This can be used in favour of getOrNull in when-cases, since the Kotlin compiler turns nullable ones into if-else chains instead of a switch table.
