Whatever optimizations you have in mind for this, could they also work for string_to_array() and array_to_string() when they get an empty string handed to them?
my idea is use string_to_array('AHOJ') --> {A,H,O,J}
empty input means empty result --> {}
As to naming, some languages use explode/implode.
can be, but if we have string_to_array already, I am thinking so it is good name.
