#5085: ST_Letters returns NULL all the time

Component:  postgis  |    Version:  master

 I was going to add some examples to manual and thought I would use
 ST_Letters, but it always returns NULL even using the example from the
 manual
 http://postgis.net/docs/manual-dev/ST_Letters.html

 {{{
 SELECT ST_Letters('Yo');
 }}}

 When I try the original from here:
 https://gist.githubusercontent.com/pramsey/2020ef463a8880edc7e23c56420d7df8/raw/dc53082cbe7c62e0a2eebf7ce32502576d281767/postgis_word.sql



 {{{
 SELECT ST_GeomFromWord('Yo');
 }}}

 that works.
