Answer 1

I like this answer explanation. You can use:

REGEXP_REPLACE(NORMALIZE(text, NFD), r'\pM', '')

As a simple example:

WITH data AS(
  SELECT 'brasília / paçoca' AS text
)

SELECT
  REGEXP_REPLACE(NORMALIZE(text, NFD), r'\pM', '') RemovedDiacritics
FROM data

brasilia / pacoca

UPDATE

With the new string function Translate, it's much simpler to do it:

WITH data AS(
  SELECT 'brasília / paçoca' AS text
)

SELECT
  translate(text, "ŠŽšžŸÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðñòóôõöùúûüýÿ", "SZszYAAAAAACEEEEIIIIDNOOOOOUUUUYaaaaaaceeeeiiiidnooooouuuuyy") as RemovedDiacritics
FROM data

brasilia / pacoca
