The problem I’m having

I have a snowflake function that I’m trying to convert to a dbt macro. I don’t think dbt has the capability to do it. I want to have the functionality inside dbt and not calling a function within snowflake

What I’ve already tried

{% macro remove_special_characters(string) %}
    REPLACE( {{ string }}, '\\p{Diacritic}', '' )
{% endmacro %}

This is the snowflake function I have inside dbt.

CREATE OR REPLACE FUNCTION  {{env_var('DBT_DATABASE')}}.{{env_var('DBT_SCHEMA')}}.REMOVE_DIACRITIC_CHARS(DIACRITIC_CHAR STRING)
RETURNS VARCHAR(16777216)
LANGUAGE JAVASCRIPT
AS '
  TRANSFORMED_CHAR = DIACRITIC_CHAR.normalize("NFD").replace(/\\p{Diacritic}/gu, "");
  return TRANSFORMED_CHAR;
  ';
