Jekyll/Liquid/gh-pages, string as char array?

Question

Get an array of every character in a string, is it available?

My code attempting to do (but failed):

{% assign a = "ABC" | split "" %}
{{ a | join ',' }}

Answer 1

Your attempt is correct, is just the syntax that is not correct.

{% assign a = "ABC" | split: "" %}

{{ a | join: ',' }}
