Okay this may or may not be a "decent example" but it could be a start depending on the length of the string.
select name
, Trim(substr(name,char(name),1) || substr(name,char(name)-1,1) ||
substr(name,char(name)-2,1 ) || substr(name,char(name)-3,1 ) ||
substr(name,char(name)-4,1 ) ) eman
from
( select 'paul '(varchar(5)) name ) dt ;
Paul
