How to split string to array by individual characters?

Postgres has too many features, so sometimes is good to remind some.

Function string_to_array is well known. This function has two or three parameters. If second parameter (delimiter) is null, then input string is separated to array of characters.

postgres=# select string_to_array('Pavel Stěhule',null);
│        string_to_array        │
│ {P,a,v,e,l," ",S,t,ě,h,u,l,e} │
(1 row)
