You're seeing just the function escape_once, go back to Liquex.Filter module for more information.

Escapes a string by replacing characters with escape sequences (so that the string can be used in a URL, for example). It doesn’t change strings that don’t have anything to escape.


iex> Liquex.Filter.escape_once("1 < 2 & 3", %{})
"1 < 2 & 3"
