Yes, actually I tried it yesterday but just to be sure I tried it again
today - no errors:

....
NOTICE:  i = 9999800
NOTICE:  i = 9999900
NOTICE:  i = 10000000

Total query runtime: 2231947 ms.
1 row retrieved.


The "letters" variable used in the test (in case you have the time to
try it yourself):
letters varchar(255) :=   'юяьъщшчцфjklmnopqrstuvwxyz';

And the database definition:

CREATE DATABASE spb
   WITH OWNER = postgres
        ENCODING = 'UTF8'
        LC_COLLATE = 'Bulgarian_Bulgaria.1251'
        LC_CTYPE = 'Bulgarian_Bulgaria.1251'
        CONNECTION LIMIT = -1;


The system locale is "Bulgarian (Bulgaria)".
